18. Thomas Jane
As Todd Parker, Boogie Nights' mustachioed, up-and-coming adult-movie stud who leads Dirk Diggler further down the path of addiction and criminality, Jane is pure charisma. While the film follows most of the main characters through the Seventies, Todd is a creature spontaneously birthed by the Eighties – all verve and confidence and flash. The actor usually tends to play quieter characters in his other films; that he can be so electrifying, quick, and loud in this part speaks to his impressive range.
