Eminem will apppear on Entourage

Los Angeles, California (CNN) -- On Sunday, "Entourage" kicks off its seventh season with another round of A-list guest stars. Jessica Simpson, Eminem, Sean "Puffy" Combs, Lenny Kravitz, Drew Brees are all set to hang with the boys. And oh yeah did I mention porn star Sasha Grey will have a recurring role?

At a time when most veteran shows are losing steam "Entourage" is picking up the pace. CNN caught up with writer, director, and producer Doug Ellin on the set. He talked about the upcoming seventh season, why the guest stars keep getting better, and rumors of an "Entourage" movie.

CNN: So what is the secret to keeping "Entourage" so hip and cool? You guys are always on the cutting edge when so many shows tend to dry up after a few years?

Ellin: Well I mean, you know, I don't have any answers to that. I mean, I try to do the best I can. I've worked hard and hopefully people like it. You never know. There's been things that people didn't like that I thought were great, and things that I didn't love that people loved. So hopefully it's a good year.

CNN: Congratulations on your seventh season. I know this season we will see some crazy stuff happening. I was just interviewing Adrian Grenier and asked him about guest stars. Can you give us a little bit more about who will be on the show?

Ellin: Yeah, Mike Tyson and Jessica Simpson. I mean we have so many people I hate to leave anyone out. People that are coming this week are Eminem, John Cleese and Drew Brees. I haven't talked to him yet but he's supposedly in. I'm talking to Matt Damon to get him back from last year. We got some good people.

CNN: How did you get lucky enough to get Eminem? He rarely does stuff like this.

Ellin: Yeah, you know I spoke to him, I pitched him something and he liked it, so hopefully it all works out. He likes the show, you know in his album he's got a shout out to Johnny Drama in "Entourage," so, in his new album that's coming out in a couple weeks, so.

CNN: When do you think that scene with [Eminem] will air?

Ellin: We locked down the date, so unless he hates the script, I think it's going to be June 30. ... We got Mark Wahlberg on set and Lenny Kravitz tomorrow. Diddy, I think, is showing up. It's what I'm told, but we'll see.

CNN: When will we be seeing all of them in these episodes?

Ellin: In a month.

CNN: So next season will be the last? I heard that Mark Wahlberg was quoted as saying there will be six more episodes after the end of season seven?

Ellin: We don't know yet. I mean, hopefully we're going to try to do one more season, and then hopefully a movie if people are interested.

CNN: Adrian Grenier was telling me that there is possibly a prequel and then a sequel ahead. Can you tell us about the movie?

Ellin: Wow, Adrian said that? [Laughs]. Is he writing it? [Laughs again] I have no plans at this point, you know? It's like right now we're in the last few weeks of shooting season seven. All I'm focused on is making it good. If people like it, we'll come back for one more season. If people like [that one] then we'll try to do a movie, but I haven't thought about it at all.

CNN: But you would have the same cast of characters in the movie, right?

Ellin: Of course!

CNN: Hear a porn star is coming on?

Ellin: Well she's new. It's her first year and she's great, I think people are going to be really blown away by her. And I think they're going to be shocked, because there's nothing about her that says "porn star" and I think people are going to watch the show and go, "Why didn't they cast a real porn star?"

CNN: Well, it's a natural progression because you are in Hollywood and you want it to be as real as possible. This is the porn-star capital of the world.

Ellin: Charlie Sheen was dating Ginger Lynn when he was one of the biggest movie stars in the world. And that's where the story came from. But Sasha just did Steven Soderbergh's Movie ("The Girlfriend Experience") and she's going to break into the mainstream. I think she's going to be the first real porn star to break into the mainstream.
