26. Steven Seagal
Worst Performances: Under Siege 2: Dark Territory (1995), Exit Wounds (2001), Half Past Dead (2002)
It's a good thing that Steven Seagal can smash heads in so damn well. Otherwise, his poorly made action flicks would be completely intolerable. No matter the character's background, Seagal always ratchets up the sleaze, playing every scene with a too-cool-for-school swag that's as cheesy as it is lackluster. He's been out-acted by both DMX (Exit Wounds) and Ja Rule (Half Past Dead)—what does that tell you?
