Courteney Cox told TV Guide that her former TV "Friend" has been asked to appear on the show during November sweeps, and on Monday night, a rep for ABC confirmed to Access the deal has been finalized.

The former "High School Musical" star has signed on to star in an as-of-yet untitled thriller, according to The Hollywood Reporter.

"It has the potential to happen," he told Access on Thursday.

LOS ANGELES, Calif. -- With his breakout role in the charming and very funny new comedy "17 Again," teen idol Zac Efron is basically sending a not-so-subtle message to anyone in Hollywood who will listen: bye-bye "High School Musical," hello movie career.

Otherwise, "17 Again" could best be described as a hodge-podge of past "what if" films, like "Big," "13 Going on 30," the similarly-titled "18 Again" and both versions of "Freaky Friday." But it's still a good movie, thanks to a charming screenplay by Jason Filardi ("Bringing Down the House"), vibrant direction from Burr Steers ("Igby Goes Down") and a star-making performance by Efron.

"I was just focused in high school... that probably made me a nerd, but I got good grades," Zac told Access Hollywood's Dish Of Salt Laura Saltman at the "17 Again" movie junket over the weekend. "I didn't really care about being the coolest kid in high school, that wasn't my priority."
