4. Russell Crowe, 'Gladiator'
In other hands, Ridley Scott's neo-biblical epic would have just been another sturdy summer blockbuster. But Russell Crowe, who had earned kudos for previous dramatic roles in L.A. Confidential and The Insider, brought gravitas and heart to his role as an honorable Roman general who must defeat the bratty young emperor (Joaquin Phoenix) who banished him to a life in the cutthroat world of the kill-or-be-killed arena. The 21st century hasn't produced many soulful, brooding, broad-shouldered action heroes, nor has it yielded a lot of popcorn movies with the scope and heart of Hollywood's old-fashioned epics. Crowe and Gladiator are the exception, a rare example of a performer rising to the challenge of making a swords-and-sandals event movie that has emotional breadth. His Maximus brings down a corrupt leader — and in the process, the Aussie actor earned his place among a new generation of superstars.
