After the second season of That 70s Show, he broke into movies filming his first movie in summer 2000.He made an impressive film debut with his supporting role as Seth Abrahams in Traffic, Steven Soderbergh's epic and widely acclaimed look at the American war on drugs opposite Erika Christensen and Michael Douglas.Topher, as the work-aholic that he is, started shooting In Good Company two months later, a production written, produced and directed by the Weitz brothers where he stars opposite Dennis Quaid.
His acclaimed work in Traffic saw his popularity further increased, acting as another testament to the beginnings of a promising career.
The movie amassed 4 Academy Awards and 2 Golden Globe Awards.
He was cast in That 70s Show because the show's creators, Bonnie and Terry Turner, had seen him play Pseudolus in a high-school production of A Funny Thing Happened on the Way to the Forum (their daughter attended the same high school as Topher).
Apart from school plays, Topher had absolutely no acting experience before landing the role of Eric Forman, a level-headed and predominantly wholesome high school student coming of age in Me-Decade Wisconsin.
The movie directed by Mike Newell and starring Julia Roberts was filmed in winter 2002.
