10. Ben Stiller
Born into an acting family, Ben Stiller harboured early aspirations for directing as well as following in the comedic footsteps of his father Jerry, with early credits in his career including 1996's The Cable Guy. It was a series of acting roles around the turn of the Millennium, however, that turned him into a household name, with roles in Theres Something About Mary and Meet The Parents paving the way for directorial roles in the hit 2000s comedies Zoolander and Tropic Thunder. Though his upcoming projects all see Stiller solely in acting capacities, the opportunity for further directorial opportunities will certainly not be denied to him by producers on the basis of his existing output.
