We all knew celebs make big bucks for appearing in films, on TV, in commercials, in video games, and for just showing up at night clubs. But according to this recent comprehensive examination of Hollywood salaries by THR, some stars make way more than we ever realized, while others make significantly less. 
 
 Here are 12 of the most surprising things we learned from the report… 
 
 Robert Downey Jr.'s 'Iron Man' Payday Is Bonkers 
 
 The Iron Man series is one of the most successful film franchises ever, so it shouldn't come as a shock that he would get good money. But $75 million is a lot, no matter who you are. How did he make that much? Part of his deal included getting 7% of the film's total gross. 
 
 Leo Made WAY More Than Jonah On 'Wolf Of Wall Street' 
 
 While they both got Oscar nominations for their role in The Wolf Of Wall Street, they didn't both take home the same paychecks. Leonardo DiCaprio made over $25 million for his performance, while Jonah Hill – who wanted to be in the movie so badly he agreed to work for the union minimum – only took home $60,000. This means Leo took home a paycheck 416 times larger than Jonah's. 
 
 One Jennifer Makes A Lot More Than The Other 
 
 Jennifer Lawrence and Jennifer Aniston are two of the most successful actresses in Hollywood, and certainly the two highest-paid Jennifers. However, Lawrence's appearances in The Hunger Games means she earns $20 million more than the former Friends star. Lawrence took home $35 million last year, while Aniston snagged $15. 
 
 Endorsements Pay Crazy Amounts 
 
 Movies can make you money, but product endorsements can make you buy-an-island rich. Aside from the $75 million from Iron Man, Robert Downey Jr. took home $12 million from an HTC endorsement. Meanwhile, Jennifer Aniston reportedly makes as much on her endorsements from Aveeno and Smartwater as she does for starring in a major film. And, don't forget TV host Bethenny Frankel who landed a deal with Skinnygirl that earned her $100 million. 
 
 We Now Understand Why Liam Neeson Will Be Making 'Taken' Sequels Forever 
 
 People really love watching 62-year-old Liam Neeson kick vaguely-foreign looking people in the face. And the studio is willing to pay big. For Taken 3 – spelled TAK3N because of course it is – Neeson reportedly got $20 million.

 Ashton Kutcher Makes The Average American's Salary Every 60 Seconds 
 
 TV Stars can make bank! For his role on Two And A Half Men, new dad Ashton Kutcher is said to make $750,000 an episode, which equals out to $34,000 per minute. Meanwhile, NCIS star Mark Harmon reportedly makes $500,000 an episode, and the main cast of The Big Bang Theory, Jim Parsons, Johnny Galecki and Kaley Cuoco-Sweeting, all make $1 million per episode. 
 
 Alex Trebek Is Swimming In Cash 
 
 As it turns out, hosting a TV show for 30 years can pay off. While most primetime game show hosts make around $75,000 a week, Trebek is clearing $10 million per year. 
 
 Jon Stewart Is The King Of Late Night Paychecks 
 
 Jimmy Fallon is reportedly making around $15 million a year. Currently, Stephen Colbert makes around the same amount, but could move up when he replaces David Letterman in a few months. And Seth Meyers apparently only clears $3 million a year. Leaving Jon Stewart, host of the wildly popular and influential Comedy Central series The Daily Show, as king of the late night mountain with his $25 to $30 million annual salary.

 Reality TV Pays Nothing, Unless You're A Kardashian Or A Member Of The Duck Dynasty 
 
 Sure, Kourtney and Kim Kardashian reportedly signed a three-year deal with E! for a solid $40 million, and the Robertson family, featured on the popular A&E series Duck Dynasty allegedly make $200,000 an episode. But they are reality royalty. You average contestant on a reality competition show, or even those who appear on a docu-series, make close to nothing. 
 
 The Sad Stat About An Actor's Average Earnings 
 
 Are you an aspiring actor? If so, you might want to skip this one, because it's only going to make you sad. Let's just quote THR, "According to the most recent SAG statistics, the average member earns $52,000 a year, while the vast majority take home less than $1,000 a year from acting jobs." Ouch.

 Everyone Short On Cash Should Try To Be An Extra 
 
 Extras, those people who just sort of mill around in the background of shots and often mess up continuity, often make $148 a day. Also, they get a $50 bump if they have to work in uncomfortable conditions. And, if the shoot goes over 16 hours (which isn't uncommon), they get a whole day's pay for every hour after. 
 
 A Monkey Makes WAY More Than Most Regular People 
 
 Remember that monkey on that very short-lived NBC show Animal Practice? Its name is Crystal, and it reportedly made $108,000 for appearing in nine episodes. Just try to read that and not get mad. Who does that money even go to? Does Crystal have a wild $1000 per day banana addiction?

Maybe her habit will change because she’s had a new baby? 
 
 G Jennifer Aniston: In 2010, Star reported that the Friends star shocked the help by flaunting her nakedness in front of them.

 G George Clooney: A few years back, Star learned the movie hunk made sure employees didn’t imbibe his pricey liquor! “He has his decanters marked so he can see exactly how much is in them and to make sure nobody ever secretly takes a swig,” confided a friend of a housekeeper.

 G Britney Spears: A source familiar with the singer’s home in 2010 said she kept a collection of sex toys in a drawer in her nightstand.

 G Demi Moore: According to a 2012 report in Star, the actress can’t bear to look in the mirror unless the lighting is perfect. “Amber bulbs are the order of the day at Demi’s house,” a source said. “She believes the softer light is more flattering.” In fact, the 50-year-old beauty hoards cases of the special bulbs in her home, scared they’ll stop being manufactured, the article reported.

 G Kim Zolciak: A 2010 Star report exposed the former Real Housewives of Atlanta star and Don’t Be Tardy reality diva as a heavy smoker who kept $1,000 Versace ashtrays lying around everywhere.

She owns a few cats and her entire home is filled with photos of them, according to a person familiar with her house. “She’s constantly grooming them to reduce the cat hair.” Many of Taylor’s clothes, shoes, and underwear feature cat patterns. And “she makes the housekeeper leave cat food and milk outside, so the neighborhood strays flock to her stoop,” the Star source reported. 
 
 G Jim Carrey: In a 2010 Star article, a household source claimed Jim is a chameleon just like in the movies. “He’s incredibly hard to work for, because you never know what kind of guy you’re going to get.

 S Miley Cyrus: Miley’s pups Mate, a white shepherd, and Sophie, a Maltipoo, weren’t very well trained, according to a mole who worked for the singer and spoke to Star about her. “They poop and pee at will in the house.” When the dogs had accidents, Miley yelled for a maid to clean up the mess. 
 
 G Kirstie Alley: The star said Cheers to pets, but her employees? Not so much—because Kirstie allegedly was never bothered when they did their business inside. “The place is often littered with what Kirstie calls ‘little surprises,’ “ an insider dished to Star. When the source spoke to the magazine, the actress had a menagerie of a dozen pets, so her home sure didn’t smell like a bed of roses! 
 
 G Bruce Springsteen: The Boss loves to fraternize with his female help, according to an insider. “Bruce hits on them constantly,” said the Star source, who claimed winking and flirting with his housekeepers, maids, and assistants was common. “If there is a woman around the house, Bruce makes his presence known!” 
 
 G Jennifer Lopez: In 2010, the mom of twins was branded so cheap that her employees called her “Pay-low!” According to the ex-worker who spoke to Star, the singer/actress expected people to slave away for her for half of what they would make elsewhere. Supposedly Jenny from the Block felt that because she once had to struggle to make it, everyone should! 
 
 G Martha Stewart: The domestic diva made her workers color the bottoms of her Louboutin shoes, a source said in Star. Martha’s staffers were kept busy because she wasn’t a fan of the signature red soles and always wanted the red changed to black with a Sharpie. 
 
 G Kate Gosselin: The reality star got so concerned about looking good that if she ran out of a certain beauty product, she would scream at the staff, according to Star.

 G Johnny Depp: The actor famous for his odd movie getups is the same at home, an insider revealed to Star in a 2010 article. “He is really into costumes,” the source said. “Johnny loves to try them on and slip into a character.” He also did it to make his then-partner Vanessa Paradis laugh by putting on her heels or dresses and walking around, the source claimed. But maybe it wasn’t so funny after all, as the never-married couple recently split after many years and two kids together. 
 
 G Madonna: In 2009, Angela Jacobsen, the former nanny for Madonna’s son, David Banda, whom the star adopted from Malawi, told an Australian TV show, “I was on call 24 hours a day.” Jacobsen said Madonna demanded that everyone in her household be on a macrobiotic diet and also revealed “there wasn’t any television in the house.” After Jacobsen was apparently reminded about her confidentiality agreement with the Material Girl, however, she clammed up! Three years later, however, another ray of light was shed on what it was like to live with Madonna. Star’s sources claimed the singer asked her assistant to get her water at least six times throughout the night, every night, and paid the employee only half of what other celebrity assistants earned.
