(ABC News) It seemed like just yesterday that the world was waiting to hear which lucky kids would fill the shoes of the literary world's most famous pre-teen wizards. Back then, Daniel Radcliffe, Rupert Grint and Emma Watson (from left at a photocall for the first movie on August 23, 2000) were just a trio of cute kids. But as they gear up to star in the fifth on-screen Harry Potter movie, "The Order of Phoenix," due out July 11 (I know, it's an old group of photos, but nobody posted them yet. - caitlin1214), it's clear that these fifth years have grown into their own. The actors' fame has had a major growth spurt that has turned three geeky wizards into teen dreams in the eyes of wizards and muggles alike. As if his years at Hogwarts weren't exciting enough -- battling dragons, serpents, and avenging war lords -- Daniel Radcliffe took on an even more audacious role when he hit the London stage... and left his knickers behind. Although Harry has definitely grown up in later books -- snogging his boyhood crush Cho Chang in book five and taking hands with (his best friend's sister) Ginny Weasely in six -- the 17-year-old actor showed off a newly buff physique in the risqué "Equus" on the London Stage. Hogwart first years thought Hermione Granger needed a charm to tame her frizzy hair and a spell to straighten her crooked teeth to complete her fiery, know-it-all style. Granger gave in to her sexy side at the Triwizard Ball in "The Goblet of Fire," shedding her oversized witches robes for a fitting, curvaceous gown. Meanwhile, the 17-year-old actress has grown up -- and out -- much more than the Daily Prophet has let on, a bit of magic that has not gone unnoticed in the eyes of 17-year-old boys.
