Seven seasons on the sitcom “That 70’s Show” led Topher Grace to roles in films like “Traffic,” “In Good Company,” “Win A Date With Tad Hamilton,” and “Valentine’s Day.” He then told his agents he wanted to work exclusively with great film artists that inspired him. Worthy projects like “Interstellar,” “Truth” and “War Machine” followed. Grace’s next chapter continues this year with the challenging role of David Duke in Spike Lee’s “Blackkklansman."
