Tambor made his film debut with a memorable turn in ... And Justice for All (1979), playing Al Pacino's emotionally unstable law partner. But Tambor's talents truly gained traction on the small screen, where he eventually earned four Emmy nominations as Garry Shandling's annoying sidekick Hank Kingsley on "The Larry Sanders Show."
In 2003, Tambor joined the cast of the critically acclaimed "Arrested Development," playing a dual role as incarcerated Bluth family patriarch George Sr. and his pot-smoking twin brother, Oscar. Tambor's performance drew two more Emmy nods and a pair of Screen Actors Guild ensemble honors.
