19) Charles T. Baker, Planet 51
Planet 51 is one of those weird movies that felt like the kind of thing people signed up for when they wanted a third house. In this animated film from 2009, Johnson plays a hapless astronaut who crash lands on a planet full of alien life, and the usual fish-out-of-water/alien-on-Earth hijinks ensue. We’re not saying anyone phoned it in on the voice acting in this film, but it certainly didn’t make anyone a standout. This is the least Rock he’s ever been, as he’s both animated, a wimp, and kind of useless as a character. Without the presence of Johnson on screen, his charisma doesn’t come through, and he loses some of his charm. He tried, sure, but this role is entirely forgettable, considering how much better he is in other roles.
