Will was walking around the set yesterday sporting the bountiful 'do, while surrounded by cast members and extras who were also getting into the spirit with full 70s garb.
The movie, "Semi-Pro," stars Ferrell as an ABA owner/player/coach, and Will has been preparing for the role by setting up his own pickup game in Hollywood. One TMZ staffer has actually played in the game and reports that Will is quite the baller. Stunt double? He don't need no stinkin' stunt double!
