Daniel Radcliffe "Wept Like a Child" When Harry Potter Wrapped - Us Weekly

Harry Potter's Daniel Radcliffe might just be the only one not looking forward to his summer vacation.

Once the 21-year-old actor premieres the final Harry Potter film — Deathly Hallows Part II — he'll have nothing but time on his hands. A tough thing to get used to, given the fact that he's used to spending all day on the Potter film sets.

"It feels very, very strange to not be going back to work with [the Potter cast and crew] next year," Radcliffe tells Larry King in a revealing interview with his Potter cast mates Rupert Grint and Emma Watson, set to air July 10.

Radcliffe — who recently revealed to GQ U.K. that he battled an alcohol addiction while filming Potter — picked up his first wizard wand at age 11, in 2001, and says that his 10-year bond with his coworkers will be hard to break.

"I've had such an amazing time on Potter. It's been such an extraordinary experience to work with, essentially, the same group of people for 10 years. You develop such close bonds with so many people."

While Radcliffe admits he "wept like a child" as filming for Potter's eighth film wrapped, his costar Grint managed to keep his emotions in check.

"The last day was a weird one," Grint, 22, tells King during the CNN special. "I wasn't…prepared for kind of how it would feel. It was kind of like the last day of school, and I remember packing up my dressing room and putting [away] all these kind of odd birthday cards and toys that I'd kind of collected over the years. It did have this really kind of final kind of feeling about it. It took a while for me to get used to not having [Harry Potter] in my life."

CNN Presents: A Larry King Special — Harry Potter: The Final Chapter airs July 10 at 8 and 11 p.m. (EST)
