Zac Efron as Mike O'Donnell Credit: New Line Cinema

20-year-old Zac Efron will turn Seventeen Again in his new dramady film as he goes back to high school. Zac plays a star athlete with great college potential (uh, can we say "High School Musical"?) but he gives it all up to marry his high school sweetheart. Jump forward 25 years and he's an adult (played by Matthew Perry of "Friends") and his marriage and career have fallen apart. His own teen kids don't have real relationships with him. Bummed, he goes back to his old school and, through some magic that we won't disclose here, becomes his 17-year-old self again! You can imagine the can of worms this opens up! Playing his daughter is Michelle Trachtenberg of "Buffy" fame.

TeenHollywood trekked out to the Santa Monica pier and Zuma Beach earlier this year to watch a party-on-the-beach-around-the-campfire scene being shot. Whoops! There's sand in our eyes and a freezing, 40 mph wind blowing!! So, no shoot tonite but Michelle and Zac were kind enough to stick around and chat with us briefly anyway in Michelle's trailer on set. We knock on the door. Let's set the scene; Michelle answers wearing her own clothes; jeans, gray boots, brown leather jacket, t-shirt, gold necklace and a long Burberry wool scarf against the wind. She invites us in and is an amazing hostess. Zac will join us shortly....
