Ron Weasley's Transformation
"I have ginger hair," was Rupert Grint's simple explanation of how he scored the role of Ron Weasley. Clearly, the powers-that-be saw more in the young actor than just a convenient hair color--costar Emma Watson even jokingly groused that he only did three auditions to her eleven. And, luckily, Grint has grown into the role, literally towering several inches over Watson and Daniel Radcliffe, thus embodying J. K. Rowling's vision: "He was tall, thin, and gangling, with freckles, big hands and feet, and a long nose."

Ron exhibited his "flaming red hair" (and an appropriately dirty nose) on the Hogwarts Express.

In the second movie, a broken wand (and a failed spell) caused the "freckle-faced, red-haired, long-nosed someone" to burp up slugs in a kid-favorite gross-out scene.

The "tall and gangling" Hogwarts student added a few inches to his height with a rumpled head of hair.

Ron's grown-out locks suited him better than the hand-me-down formal robes (complete with '70s-style ruffled shirt) he would be forced to wear to the Yule Ball.

"He seemed to have grown several more inches during their month apart, making him taller and more gangly looking than ever," Rowling wrote of Ron. In keeping with his character, 19-year-old Grint was clearly more man than boy in the fifth film.

Ron became an athlete in the sixth installment-bounding into position on the Quidditch field-and his crush on Hermione grew stronger. "There's more for me to do, which I'm really pleased about," Grint told Entertainment Weekly. The actor even made off with some Hogwarts memorabilia during the last flick filmed in the school: "I managed to swipe one of my ties as a souvenir."

Ron took a beating in the first half of the final installment, but Grint took his character's physical struggles (which included filming on cold wet sets) in stride. As he said to EW, "It's a little bit annoying, but...these films have given me opportunities I never would have had, and I kind of got into this flukily, so I'm just grateful to have been a part of it."

In the final movie, Ron is forced into a brutal battle. "This is a war movie," Grint told EW. "Lots of things blowing up. Lots of bodies buried in the rubble."
