A six-time nominee and one-time winner, Piven has one more chance to triumph for playing Ari Gold, whose final season of the series showcased a softer side of the super agent.

UPDATED: Currently filming the "Entourage" movie, Piven revealed how he was overshadowed by the "Sherlock" star at a critics' Q&A.

Jeremy Piven was the special guest on Jimmy Kimmel Live! on Wednesday, and while he is currently shooting his most famous role in the Entourage movie, it was the PBS series Mr. Selfridge that he was most keen to talk about.

"It is like Willy Wonka meets Tom Ford -- if you take mushrooms you can appreciate that," he told Jimmy Kimmel, in his strange description of the period drama that tells the story of the founder of London department store Selfridge & Co.

"PBS is putting it out and we went and did a Q&A for the critics and they said we were going to share it with Sherlock," explained Piven, who was told: "'You'll do your Q&A, they'll do theirs, then we'll put it out to the critics and if they have any questions they will come to the stage and ask you or Sherlock questions.'

"They guide me to the stage in the dark and when the lights come on they say, 'Please give your questions to Sherlock,' and they forgot to say Mr. Selfridge. I am standing there on the stage while hundreds of people made their way to Benedict Cumberb----," he joked as ABC's censors beeped out his obscene version of the British star's name.

"By the way, he is a brilliant actor and a true gentleman and Sherlock is genius. I am a huge fan and he'll never speak to me again!" Piven said, adding that being ignored by the masses on stage "was so humbling and horrifying."

Earlier in the show, Piven dished about the happenings on the star-filled set of Entourage, which he described as "unbelievable, I am having a great time."

"I was driving a red convertible as Ari Gold the other day and pulled up next to Liam Neeson [who is a guest star] and we're doing our scene, and I hear laughing -- I suddenly realized that the paparazzi were hidden in the bushes are laughing at the script," he said.
