“Entourage,” the much-anticipated big-screen version of the award-winning hit HBO series, reunites the hit show’s original cast, led by Kevin Connolly, Adrian Grenier, Kevin Dillon, Jerry Ferrara and Jeremy Piven.

Movie star Vincent Chase (Grenier), together with his boys, Eric (Connolly), Turtle (Ferrara) and Johnny (Dillon), are back...and back in business with super agent-turned- studio head Ari Gold (Piven). Some of their ambitions have changed, but the bond between them remains strong as they navigate the capricious and often cutthroat world of Hollywood.

At a recent press conference in Los Angeles, the cast (minus Jeremy Piven, who was tied up with his current show “Mr Selfridge”) and writer/directed Doug Elin discussed reuniting, capturing life in Hollywood and what the series has meant to people. Here’s a sampling of what was being said.

You guys have been together for 15 years, how has the essence of your character changed?

Kevin Dillon: My character has changed the least amount and is still striving for the same thing which is fame. Not really fortune so much, he’s really about the fame. That’s what I love about him, I don’t want him to change too much.

Adrian Grenier: One thing about this crew that’s so special is despite all the changes and all the ups and downs, there is still something that remains steadfast which is their loyalty to each other. Vince has certainly inspired a generosity amongst them.

Jerry Ferrara: I think turtle is the last to start the evolution process but I like to go back to the early, early years of the character where he was telling girls to make out with him and show them where Vince eats breakfast in the morning, to dating Jaime Lynn who was out of his league to basically being a millionaire. I used to joke around with Doug (Ellin) all the time asking when is Turtle going to grow up a little more and this was in season 2 and he said in season 8. So when we got to season 8 I told Doug that it was time. But I love the evolution of this guy and I’ve matured a little bit as he has too.

Kevin Connolly: I think all the characters have evolved, when you look at season one compared to season 8, I think Drama has become a bit more evolved too. Of course E and Sloan are taking a big jump in this one and adding a tiny member to the entourage. It’s a big step for anybody in real life.

Emmanuelle Chriqui: It’s been an incredible journey for the characters. For me it’s been six seasons. I’d say Sloan was a little more naive in the beginning. As E and Sloan’s relationship evolved so did so many conflicts and things that we worked through. It’s just nice that come the movie – they’re too real adults.

Haley, could you talk about being the newcomer to the group?

Haley Joel Osment: It was a lot of fun to come in and play a character who’s just a total asshole. Doug created a really fun character, in Travis McCredle, who comes in and tries to insert himself in a world where he doesn’t really belong. It was a really, really fun project to work on. It was very enjoyable.

Was there ever a fear that people not in the entertainment industry would not get the little stuff in the film?

Jerry Ferrara: I used to wonder if some of the jokes and lines would get lost to people who didn’t live in LA but you’d be surprise how many people are obsessed with the inner working of the business. You would just wonder if they’re getting it.

Kevin Connolly: I remember after we did the Sundance episode and getting calls from ten of my friends from Long Island telling me they’re now going to Sundance. I told them no you’re not going to Sundance, you’re not going to get it, you’re going to be standing outside in the cold, so don’t do it! We’ve open a lot of people’s eyes to the different aspects of the business.

Adrian Grenier: It’s also a testament to how layer the show is, even if you don’t get the jokes you can still enjoy it.

Kevin Dillon: I remember telling Doug that I wasn’t sure if anyone was going to get this outside of Hollywood and he didn’t care and said the audience will figure it out.

Kevin Connolly: We’ve made the traffic worse in LA. We’re responsible to tons of people moving out to LA because of the show and I tell them, “are you carpooling?” Lots of people have looked at us as a group and said if these guys can do it so can they.

You guys had so many cameos in this film, how did the process work and did you send out a wish list?

Doug Ellin: None of it is done for stunts or to get extra people to come in. It’s done authentically, to the way of life out here, and certainly to the life of a movie star.

We had [New England Patriots’] Rob Gronkowski waiting around to do his scene, and it was like a party. I asked him if he minded waiting a little bit for his scene. He said he’d hang out all day. At the end of the night we had Rob Gronkowski serving soup to the extras because he was having a great time.

Liam Neeson was different because he was on one of our wish lists. I called his people and asked if there was any way to get Liam in this movie.

It was like when we tried to get U2 on the show. It was a joke; we said can someone go and get U2? And somehow we got ‘em. And then we got the call that Liam was in, I think maybe because his son loved the show. So Liam showed up and he had a great time.

These guys don’t do it for the money, because we’re only paying them union rates (laughs). We’ve always had people who want to be there. So it’s been a pleasure.

“Entourage” delivers the same cleverness and humor from the show along with the usual bonds of bro-ship, partying, sexy ladies, and some Hollywood inside jokes. The Drama-dy and Ari Gold steal the spotlight. If you're not a fan of the show, you probably won't like the film, as it plays like several episodes back to back. We've been here before, but its great to be back!
