U.S. actor Zac Efron takes another step away from the world of high school musicals that made him famous with a part in "Me and Orson Welles," which also features British newcomer Christian McKay in the title role. In the movie, which hits British theatres on December 4, 22-year-old Efron plays a teenaged student who fortuitously stumbles into a minor role in the 1937 Mercury Theater production of "Julius Caesar" directed by the young Welles.

During one tumultuous week, he makes his Broadway debut, finds romance with an ambitious older woman and dares to cross the overbearing Welles in a coming-of-age tale. The film is Efron's second release since he graduated from the successful "High School Musical" franchise which made him a teen idol, after he appeared in "17 Again" which came out in April."I'm definitely sad to see the end of it (High School Musical), but I think it's all about progression and growing and trying new things," Efron told Reuters on the red carpet of the new movie's European premiere in London late on Wednesday.

Other stars at the screening included Strictly Come Dancing celebrity Ali Bastian and her dancing partner Brian Fortuna. The pair, who have been rumoured to be having a romance, played up to the cameras, with Ali cosying up to the dancer and kissing him on the cheek. Zac's new movie is a move away from his comedy and musical roles. The drama was filmed on the Isle of Man, and fans flocked to the remote location to try and catch a glimpse of the star.

Since Twilight mania began taking hold last year, everyone from Zac Efron to Kelly Clarkson to Joe Jonas have raved about the franchise.

Welcome to Thursday's gossip! This has sexy potential. Robert Pattinson describes the glorious moment he first came face-to-face with the man of his dreams, Zac Efron: "He was a really cool guy. That was one of the first times I'd ever been star-struck, but just because his face is so specific, it's kind of surreal." Since I was only able to locate one picture of them together in the history of wire images [fig.1, below], I'm pretty sure they didn't actually bang, but, sigh, let's pretend.

Let me just say off the bat, I have never seen High School Musical 1, 2 or 8. I'm one of those people who will automatically dislike someone or something if it's overexposed (except you R.Pattz...heart ya). That's how I felt about Zac Efron initially. I just didn't get what the hype was about aside from his too perfectly placed hair.

Then I saw Zac do Saturday Night Live, which he rocked, and also saw his schtick on Entourage. That's what made me start to realize he wasn't another teenybopper douche bag and actually had a sense of humor. Hence, when I shamelessly became a Zefron fan.

ROBERT Pattinson admits he got starstruck when he met Zac Efron. The hunky Twilight star says he was lost for words when he first crossed paths with the High School Musical actor.

I met Zac Efron,” Pattinson told Britain’s OK! magazine. “He was a really cool guy.

I’d like to meet Jack Nicholson. Rob, 23, recently revealed that he regrets having dental work for his role as vampire Edward Cullen. “They tried to fix my teeth,” he said.

And they shaved these little gaps on, they tried to do an Invisalign thing. And I put the Invisalign thing on and was like, ‘I don’t wanna wear that s t’.

Those gaps between my teeth have decayed and caused me so many problems. That’s the one thing I regret doing because I wasn’t thinking at the time.”
