We live in an era where the vast majority of tentpole releases are films based on existing properties. The drive to attach a recognizable name to a movie has even transformed toy lines into films. Sometimes this is a success, such as in the case of "Transformers." And sometimes it does not, like with the "G.I. Joe" franchise. While that series did see two films, they were very different, as the hero of the first was killed off in the sequel. Channing Tatum admits that happened because he never wanted to make the movies in the first place.

Speaking with Vanity Fair while literally attached to a polygraph machine, Channing Tatum was asked if the decision to see his "G.I. Joe: The Rise of Cobra" character Duke killed off in the first 10 minutes of the sequel was his idea. He says it was, and the polygraph seemingly confirms it. When asked why, he explained that he only made the first "G.I. Joe" film because he was under contract to do so, so he jumped ship from the sequel as quickly as possible.
