Eventually, the studio's collection grew to include items as varied as Betty Davis costumes, several versions of the Batmobile and the original storyboard from the 1957 Bugs Bunny cartoon "What's Opera, Doc?"
The studio's museum opened in 1996 and is accessible only to visitors who register for a VIP Studio Tour, Historic highlights from the collection are on view alongside current memorabilia, such as pieces from the 2009 superhero film "Watchmen."
There are also props from the Harry Potter films, including the entire cupboard under the stairs, the Goblet of Fire, Tom Riddle's diary, magic books and robes. "We call it the disappearing Harry Potter exhibit," Adams says. "Whenever the next film needs something, we send it back."
