That 70's Show
Kutcher's portrayal of the bumbling but lovable Kelso on the Fox comedy series that also starred (from left to right) Laura Prepon, Danny Masterson and Wilmer Valderrama made him into star. Of the role, Kutcher says that growing up in Iowa helped him understand his character's small-town frustrations.
