18. Milla Jovovich
Worst Performances: He Got Game (1998), Resident Evil (2002), Ultraviolet (2006), The Fourth Kind (2009), The Three Musketeers (2011)
There's a difference between convincingly kicking ass and handling a dramatic moment. When it comes to the former, Milla Jovovich is hands down one of the best in Hollywood, male or female. Look no further than the never-ending Resident Evil franchise. But stick the model turned actress into a role that requires her to unclench her fists and portray an average human and the results, as seen in The Fourth Kind and Faces in the Crowd, will leave you wishing that someone would just throw a punch at her and get it over with.
