Before Tim Burton’s 1989 Batman movie, Batman was largely known for the campy Adam West/Burt Ward TV series. In fact, they wanted to make a Batman movie based on that show called Batman in Outer Space. Luckily, two movie producers bought the rights and wanted to make a darker version of Batman's story. In the mid-80s, after the success of Ghostbusters, director Ivan Reitman was attached to direct and he wanted to cast Bill Murray as Batman and Eddie Murphy as Robin. These are just some of the facts packed into the latest episode of You Think You Know Movies, which heads to Gotham with the original Batman!

While the Bill Murray/Eddie Murphy movie never got made, Warner Bros. eventually hired Tim Burton, who wanted Michael Keaton to star. Keaton was primarily known for his comedic roles and his casting caused a major controversy. If you think that modern comic book fans are the only ones to complain about casting, back in 1988 angry comic fans sent over 50,000 handwritten letters to the Warner Bros. offices complaining about Keaton as Batman. Sound familiar Batfleck?
