Hollywood assistant accidentally shares A List info and hilarious messages ensue An assistant to Hollywood producer Nathan Kahane on Tuesday learned the hard way the value of the BCC option when sending a mass e-mail. Nathan was the producer of films such as This Is The End, Juno and Last Vegas and left it up to his assistant to let his Hollywood pals know about a change of address. The assistant sent out an e-mail letting some of Tinseltown's biggest names know that Nathan was moving his production company Good Universe from Santa Monica to Beverly Hills. E-mail mishap: Film producer Nathan Kahane, shown at an Oldboy screening in November with actress Carli Norris, accidentally shared the e-mail addresses of more than 200 Hollywood movers and shakers The only problem was that the assistant CC'd the e-mail to the movers and shakers in Nathan's address book whose initials have either an A or a B, according to an article on Tuesday in Gawker. The error meant that all the recipients of the massive e-mail received the e-mail addresses of studio heads such as Disney's Sean Bailey and New Regency's Pam Abdy. Celebrities such as Judd Apatow, Casey Affleck and Warren Beatty also had their e-mail addresses exposed for all to see. On the list: Hollywood producer Judd Apatow, shown on Monday in New York City, responded to the mass e-mail with a Gawker reference The 46-year-old Judd has produced hit comedies such as Bridesmaids, Pineapple Express, Knocked Up and The 40-Year-Old Virgin and replied to everyone naturally with a joke. I just made a hundred grand selling this contact list to gawker. Should we split it or donate it to water.org? Judd responded referencing the media news and gossip site. He also asked the e-mail recipients for a photo of Nathan. 'Gawker requested something casual (from a Lakers game?),' he joked. E-mail recipient: Warren Beatty, shown in 2011 in Los Angeles, was among the more than 200 people whose e-mail addresses were accidentally shared Lionsgate executive Michael Burns had fun with the mishap. I have a very sweet picture of Nathan on a pony I will send. Best to all,' he responded. Josh Brolin starred in last year's Oldboy produced by Nathan and also responded to the mass e-mail. You just gave my email to 260 people. Awesome! 8x10s on the way!,' the 45-year-old actor wrote. Facetious response: Oldboy star Josh Brolin, shown in October in London, called the sharing of his e-mail address 'awesome' The e-mail blast also included Art's Deli in Studio City and they invited Hollywood's finest to join them for a meal. 'And I am expecting Josh's signed photo when he visits! Thank you for including us in your emails today!,' a deli staffer replied. For those not in the know, CC stands for carbon copy and includes e-mail addresses of recipients allowing for all-to replies, while the BCC option stands for blind carbon copy and only provides the sender's e-mail address. New York City-based Gawker clarified in its article that it didn't pay Judd $100,000 for the e-mail chain.
