With his incredibly juvenile -- but, yes, sometimes you can't help laughing -- "Robot Chicken" animated comedy show setting ratings records this month for the Cartoon Network's Adult Swim (Teenage Boy Swim would be more like it), Seth Green has more ambitions. For one thing, he reveals he's been back to George Lucas's Skywalker Ranch, to talk about a follow-up to the wacky "Star Wars" send-up of earlier this year.

For another, "There's one actor we're holding out for," says Seth, speaking of himself and partner Matthew Senreich. "We've been trying to get Kiefer Sutherland for the entire season. He said he was interested in doing it, but you can imagine (how hard that is) with his schedule, starring in and producing '24.' We waited for last season to wrap up, but then he was prepping a movie in Eastern Europe," he adds, meaning Sutherland's "Mirrors" horror film. "And after that, you know, you just desperately wanted some kind of break. Talk about the hardest working man in show business! But we love him, and we really want him, and we'll wait. We make it very easy to record. We say, 'We'll come to your trailer for 15 minutes.'"

Already, a long list of celebs, including Ashton Kutcher, Hugh Hefner, Scarlett Johansson, Jimmy Kimmel, Lance Bass, Snoop Dogg and George Lucas himself, have lent their voices to "Robot Chicken."

Lately, Green's been juggling his very full "Robot" schedule with work on the big screen "Old Dogs" comedy with John Travolta and Robin Williams -- and looking forward to finishing up a couple of his own script projects after that. What is not on the front burner for Green is "The Brazilian Job," a sequel to the hit 2003 "The Italian Job." "I've read two different scripts for that -- one a really great one -- over the last four years, but nothing has been greenlit. There've been three different heads of Paramount, and none of them has made it a priority. And it would be really difficult to get all the people back together again."

IF AT FIRST YOU DON'T SUCCEED: "Harold & Kumar Go to White Castle" was a bust in its theatrical release, but star John Cho tells us fans now can't get enough of the quirky movie, which has made its way into a sequel coming out next year. "I've been shocked by just how many people have seen it, which is weird because it didn't do all that well at the box office, but it's been doing very well on DVD," notes Cho, who recently teamed up with co-star Kal Penn to film "Harold & Kumar 2" about the hapless pair trying to go to Amsterdam. "It's like an old sock. Oh, wait, that's disparaging. Let me change the metaphor. It's like riding a bike," he says of reprising the roles. "It certainly was easier the second time around because there was no finding footing. It's got all the things you like from the first one, but bigger and better. I will reveal that it takes place immediately, like seconds, after the first one."

For now, Cho is hitting the TV circuit with guest spots on "Ugly Betty" and a three-episode arc on "Til Death" starting Oct. 3. "You don't know how short you really are until standing in Brad Garrett's big shadow," he says about working with the show's 6 foot, 8 inch star. Cho plays a vice principal, which wasn't too much of a stretch for the one time teacher. "My first year out of college I taught at a private school in L.A. I'm not sure how much I informed them, though. Thankfully acting worked out. Working at a school is definitely more chaotic, but I have the utmost respect for teachers."

SUNRISE, SUNSET: Ethan Hawke says fans haven't given up asking whether he and Julie Delpy will reunite to continue the story of lovers Jesse and Celine of "Before Sunrise" (1995) and "Before Sunset" (2004) -- particularly since the last chapter in filmmaker Richard Linklater's movie romance ended ambiguously. "I'd be shocked if we don't make another one," Hawke says. "The question is when. Will it be when they're in their 40s -- or 70s? When it does happen, I'm sure it will happen the same way the second film did. We talk, we daydream about what it might be. We're waiting 'til we have something else to say with these characters, what the next chapter is." He makes it clear he'll be delighted to return to their world: "I love those films."

TAKE TWO: Tia and Tamera Mowry's "Twitches Too" movie airing on the Disney Channel Oct. 12 might end up clearing up some confusion for their younger fans -- or not. When repeats of their "Sister, Sister" sitcom of 1993-1999 started showing on the Disney Channel, "a lot of kids thought it was a new, fresh show," says Tia. "I had parents walk up to me and say, 'My daughter wants me to take her to a taping.'" Nowadays, she says, her original "Sister, Sister" fans "have followed me into 'The Game,'" the CW series in which she plays the fiancŽ of an NFL player. Meanwhile, the now-29-year-old twins are back to playing 21-year-olds in "Twitches Too," picking up the storyline from their popular "Twitches" 2005 Disney Channel movie about a identical twin witches who discover their true identities the day they come of age.
