Disney Channel will premiere the highly anticipated "Teen Beach Movie," a modern take on classic beach party movies, FRIDAY, JULY 19 (8:00 p.m., ET/PT). The movie trailer will debut exclusively on Disney.com (3:00 a.m., ET/12:00 a.m. PT) and on Disney Channel (9:00 p.m., ET/PT) on FRIDAY, MARCH 15. Starring are Ross Lynch (of Disney Channel's "Austin & Ally" and Hollywood Records' R5) and Maia Mitchell (ABC Family's upcoming "The Fosters") as Brady and McKenzie, surfers who take the last wave of summer, one that mysteriously takes them into a classic beach party movie, Wet Side Story. There, it's surfers versus bikers for control of the beach hangout…and everyone spontaneously breaks into song and dance. Brady and McKenzie must try to return to present day, but their lives may be changed forever when they inadvertently change the movie's romantic storyline -- and the movie's handsome surf guy, Tanner, is falling for McKenzie while biker girl Lela is swooning for Brady.
