6. JOHN TRAVOLTA AS JAN SCHLICHTMANN IN A CIVIL ACTION (1998)

A personal injury lawyer, Schlichtmann isn't driven by outrage that a big company has been poisoning people and the environment; the only green he cares about goes in a billfold. After initially turning the case down because he doesn't see any money in it, he signs on when he realizes that several of the defendants are filthy rich. So yeah, don't expect dude to come to your Earth Day party.
