Zac Efron eager to star in 'Memphis' movie

Zac Efron is keen to star in a movie adaptation of the Tony-winning Broadway musical Memphis.

The High School Musical heartthrob attended the performance, his second visit to the show in a month.

His girlfriend, Vanessa Hudgens, accompanied Efron, as well as Adam Shankman, a judge on So You Think You Can Dance and the producer of Efron's flicks Hairspray and 17 Again.

Insiders speculate that Efron is interested in the lead role of Huey Calhoun, a 1950s-era Memphis radio DJ played onstage by Chad Kimball.

Sources said Efron hung out with the cast during intermission and gushed over female lead Montego Glover.

"When Montego came over, Efron said, 'I just can't stay away from the show," the New York Post quoted a witness as saying.

A representative for Memphis confirmed that Efron has attended the show twice.

Efron's representative had no comment.
