Ali

2. Will Smith (Ali)

If you’re going to tell the story of the greatest professional boxer of all time, you have to do it right.

Working with Sugar Ray Leonard’s former fitness coach, Will Smith rose to the occasion, turning his 185-pound frame into 220-pounds of lean, sinewy muscle through grueling six-hour-a-day workouts and intensive weight training.

At his peak physical condition during the filming of Ali, Smith was benching 350 pounds while moving with the agility of a skilled fighter.Through his focused training, the rapper-turned-actor ended up with a physique just as impressive as the former World Champion.

And while the film garnered mixed reviews, Smith’s performance was praised and the actor received an Oscar nomination.
