Nickelodeon's hit animated series makes the leap to the big screen, and gets a live-action makeover in this feature that finds Timmy Turner all grown up but still mischievous as ever. Fearing that his fairy godparents will disappear if he admits his true age, 23-year-old Timmy (Drake Bell) shuns adulthood to remain in the fifth grade. Timmy's arrested development comes up for parole, however, when the once-geeky Tootie (Daniella Monet) returns home as a beautiful young woman, and finally catches his eye. But as much as Timmy wants to grow up and win Tootie's heart, he can't help but fear that Cosmo (Jason Alexander) and Wanda (Cheryl Hines) will vanish along with his inner child if he chooses the path to adulthood. Later, as Timmy struggles to make a decision, charismatic oil tycoon Hugh J. Magnate (Steven Weber) shows up in town seeking to nab the fairies and harness their power to fuel his thriving empire. ~ Jason Buchanan, Rovi
