Fans have dreamed of an Entourage movie at least since the show's finale in 2011. The HBO series is now in the process of becoming a big screen flick and is going to have the stars to back it up.

According to Jeremy Piven, who played Ari Gold on the series, uniting with Adrian Grenier (Vincent Chase), Kevin Connolly (Eric Murphy), Jerry Ferrara (Turtle) and Kevin Dillon (Johnny "Drama" Chase) has been a ball.

"I think for the people that watch the series and are fans, I think they're going to be really satisfied because everyone's back, and we picked up where we left off and then we have incredible cameos," Piven said Monday in an interview with E News.

There is at least one change in the cast, however. Ari's assistant Lloyd, played by Rex Lee, has been replaced with a new assistant, played by rapper/actor Kid Cudi.

"Kid Cudi has stepped in and is crushing it, and were having a blast," Piven, who earned three Emmy Awards as Ari, said. "Lee is still very much in the movie."

Tom Brady and Chrissy Teigen are some of the stars slated to make cameos.

"I had a very funny moment with Liam Neeson the other day where I pull up in a very under-the-radar red Ferrari convertible, and he's driving a Bentley," Pivey shared. "...and I hear almost like a laugh track while were doing the scene, and I look out of the corner of my eye and the paparazzi are laughing. The fact that they've let their cameras down for even a second to laugh means we're onto something."

Russell Wilson, quarterback for the Seattle Seahawks, will also be seen in the film, but his appearance came at a cost: Connolly's leg. While playing football with the athlete, Connolly broke his left leg in three places late last week.

"[It was] a bad break doing a scene," Connolly told E! News. "I'm on the mend."

Still, Connolly was able to work the next day.

The Entourage movie hits theaters June 12, 2015.
