Although unofficial, an "Entourage" movie sequel is close to happening if you'll ask the producers himself, Mark Wahlberg.

Even before the announcement of the release date of the upcoming bromance film, the "Transformers" star is already positive that it will have a second installment.

Wahlberg revealed upon talking to Access Hollywood that they are already planning the sequel.

"I told Doug, 'Let's not wait for the movie to come out to start planning the next one because this is definitely going to be a big success,'" he revealed. "If I have anything to do with it there will be."

The claim was backed up by "Entourage" movie star Adrien Grenier in an interview with MTV News at Sundance.

"The great thing is the movie is awesome," Grenier excitingly said.

"I think it's going to be a huge success; I think people are going to love it. We're all very proud of it. That means most likely there will be another... [executive producer] Doug Ellin has his contract to write the next one... I think he's starting to brainstorm. If you have any ideas, tweet Doug Ellin and give him some."

Not only did Grenier reveal that there is an upcoming "Entourage" movie sequel, he also claimed that fans would have a chance to give out ideas that could be featured in the second installment.

While, the news of an "Entourage" movie has been rampant over the Web, Grenier wants the fans to know what should they expect in the movie adaptation of the hit HBO series first.

"You always want a sense of escalating circumstances, especially with a series - you've got to always top your last episode," Grenier explained.

"This has to top a whole successful series. It's definitely bigger in scope. It's a film, it's a real film. The set pieces are bigger, the conflicts are a little bit more elevated, and it's going to be a fun ride."

In addition to Adrien Grenier playing Vincent Chase, Kevin Connolly, Jeremy Piven, Kevin Dillon, Jerry Ferrara, Perrey Reeves, Rex Lee, Scott Caan, Emmanuelle Chriqui, Constance Zimmer and Debi Mazar are reprising their roles for the movie adaptation.

Just like in the series, the movie is expected to feature a number of famous entertainment and sports personalities.

"Entourage" movie is set to hit cinemas on June 5, while the sequel has yet to be revealed.
