The development of the Entourage movie seems to have hit another road block as cast members Adrian Grenier and Jeremy Piven are holding out for more money, according to Page Six.

The movie was announced in January 2012. In January of this year, producer Mark Wahlberg confirmed the script was completed and they planned to go into production in May. Wahlberg was looking to have the film ready by May 2014.

"They wanted to start filming early this summer, but the cast has been on hold. Jeremy finally signed his contract two weeks ago. His deal closed Aug. 29. But there are other members of the cast, including Adrian Grenier and Jerry Ferrara, who are still holding out," a source told Page Six. 

It's been a very long while since the show and since there is no telling when the production of the film will hit the road, Enstars rounded up some updates about the main men of Entourage.

1. Jeremy Piven (Ari Gold): Piven currently stars in the PBS British period drama Mr. Selfridge, which premiered in March. It was announced in August that Piven had been cast in Tom Cruise's Edge of Tomorrow. He has even snagged a role in the upcoming instalment of Sin City. Sin City: A Dame to Kill For will release in 2014.

2. Kevin Connolly (Eric "E" Murphy): Connolly has not been acting as much as he has been directing. Earlier this year, Connolly released his documentary Big Shot and ESPN 30 for 30 production about the scandal surrounding former New York Islanders owner John Spano. Currently Connolly is directing Dear Eleanor, which stars Jessica Alba and Josh Lucas. He has also acted in John Herzfeld's upcoming film Reach Me.

3. Adrian Grenier (Vincent "Vince Chase): Grenier stars in the apocalyptic drama Goodbye World, which premiered at the LA Film Festival in June. An official release date for the movie hasn't been confirmed yet. The film also stars Ben McKenzie, Mark Webber, Gaby Hoffmann and rapper Kid Cudi.  

4. Jerry Ferrara (Turtle): Ferrara has a couple of films lined up for release and some he is currently working on. He has small roles in the Last Vegas, which releases in November, and Lone Survivor, coming out earlier next year. He has wrapped work on the romantic comedy Think Like a Man Too, which will release in June of 2014. Ferrara is currently filming for The Life.

5. Kevin Dillon (Johnny Chase): Dillon is filming Compulsion, also starring Heather Graham and Carrie-Anne Moss. He also going to be acting in the action film Twisted Metal, which is slated for release in 2014.
