Entourage movie cast Jeremy Piven admitted that reprising his role as Ari Gold for the film after the series went off the air three years ago, left him surprised and schizophrenic.

"I really had left him behind and was embracing, am embracing, this entire journey. So, it required me to be a little schizophrenic," Piven revealed during the Television Critics Association press con for winter previews on Monday.

The hit HBO TV series, Entourage aired for eight seasons that paved way for Jeremy Piven winning three Emmys for his portrayal of the hardworking Hollywood agent, Ari Gold. After Entourage concluded on September 2011, Piven has kept himself busy with different projects, particularly with Mr. Selfridge, where he played as the lead actor. The series will be returning for its second season on March 30 on PBS.

Piven has compared the two characters, telling how the two differ from each other.

"Ari Gold to play was incredibly taxing. If you're yelling for 12 to 14 hours a day and breaking computers, your body think it's real," he explained. "It's been really great to play Harry because he has this huge heart."

Ari Gold is "all bark and no bite," as compared to Harry Selfridge, the lead character from the series, which is based on the real-life founder of Selfridge & Co. department store, according to Piven. "Whereas Harry, at work, he couldn't be more professional" despite his personal indiscretions such as cheating on his wife. "His bite is worse than his bark," Piven said of Harry. "They're ultimately polar opposites of each other."

Despite the very intense role, he has to portray again for the Entourage movie, Jeremy Piven has described the screenplay of the movie "really good" and added that he's ready to bring back his modern-day designer shoes and custom-made suits for his role. "I'll jump back in," he exclaimed. "I can't tell you too much about what happens in that particular world because we have to fly under the radar on that one, but I look forward to it."

In other, Entourage movie cast update, Constance Zimmer has recently revealed that she'll be back with the boys to reprise her role as film executive Dana Gordon for the film.

"This is the first time I have officially said I am, so you guys have it!" Zimmer revealed to E! News. "My deal just closed, like a couple of days ago."

She admitted that when she learned that the Entourage movie is a go, she wanted to become a part of it.

"Dana Gordon is a part that I have lived and played for so long and I think the fact that we get to see it up on the big screen is kind of terrifying," she explained. "It's really just going to be like a whole season that you get to watch at once, so it'll almost just be like watching streaming television."
