Best Bets: 'Spider-Man' spins web with new cast By Gael Fashingbauer Cooper Happy Independence Day week! If it's hot where you are, slink inside to the air conditioning and check out a big movie, and of course, don't forget the fireworks. TUESDAY: 'The Amazing Spider-Man' The webslinger's story gets a whole new cast, with Andrew Garfield stepping in as poor Peter Parker, the hapless high schooler who gets chomped by a radioactive spider and becomes an unlikely superhero. Emma Stone plays girlfriend Gwen Stacy (comic-book readers know she came before redheaded Mary Jane Watson) and Sally Field and Martin Sheen play Peter's Aunt May and Uncle Ben. Rhys Ifans faces off against Garfield as Dr. Curt Connors, who transforms into a giant lizard when his limb-regenerating experiments go horribly wrong. It's always good to have Spidey back, and who knows? Once he gets a movie under his utility belt, he may even join the Avengers, just like in the funny pages. Opens July 3. WEDNESDAY: 'A Capitol Fourth' If you're not heading out to a fireworks display, catch all the rockets' red glare from the comfort of your couch with "A Capitol Fourth." The annual Washington concert will be hosted by "Dancing With the Stars" host Tom Bergeron. "American Idol" winner Phillip Phillips, Kool and the Gang, Matthew Broderick and others will perform at the event. July 4, 8 p.m., PBS. FRIDAY: 'Savages' Oliver Stone returns to theaters with "Savages," which has intrigued movie buffs since the first clips were revealed months ago. Aaron Johnson and Taylor Kitsch play pot growers who share a girlfriend (Blake Lively). When she's kidnapped, they have to go up against a drug cartel and a corrupt DEA agent (John Travolta). Opens July 6.
