In 2006, Dinklage co-starred with Vin Diesel in "Find Me Guilty", a courtroom drama directed by Sidney Lumet. The film tells the true story of the longest Mafia trial in American history; Dinklage played Ben Klandis, the lead defense attorney. Critical reaction to the film was mostly positive, though it was a commercial failure. Writing for "Chicago Sun-Times", film critic Roger Ebert praised Dinklage's performance, saying that the character he plays stands apart as "concise, articulate and professional." The same year, he portrayed the character Marlowe Sawyer in episodes of "Nip/Tuck". He played a fictionalized version of himself in an episode of the HBO series "Entourage" and appeared in NBC's "30 Rock" as Stewart. The same year, Dinklage appeared in the British romantic comedy "Penelope" playing Lemon, a tabloid reporter. The film received mixed reviews from critics.
