CNN announced that the one-hour special will feature interviews with Daniel Radcliffe, Emma Watson, Rupert Grint, Tom Felton, Helena Bonham Carter and Robbie Coltrane.
It will also include never-before-seen footage from 'Harry Potter and the Deathly Hallows: Part II' days before its worldwide premiere.
Additionally, James and Oliver Phelps, who play the Weasley twins, take viewers on a tour of the Wizarding World of Harry Potter at Universal Orlando and interact with fans.
The three main stars, who have spent half of their lives playing these characters, open up to King and reflect on the end of an era. Radcliffe says that he "wept like a child on that last day" of filming, and Watson says she "was still losing my baby teeth" when she started playing Hermione.
"I was so young, it's difficult to remember much of my life before this thing happened to me," she says. Grint tells King that after spending ten years of his life playing Ron Weasley, it was "quite a big kind of shock" to leave him behind.
'Harry Potter and the Deathly Hallows: Part II' is the most hotly anticipated movie of the year, and it marks the end of the most successful movie franchise ever.
CNN promises that King will take viewers on an exclusive tour behind the scenes and into the making of the final movie with the special effects team who brought the magical world to the big screen. Previously unaired footage will give viewers a new glimpse at the iconic characters and, for the first time, fans will see an extended clip from 'Part II.'
'A Larry King Special -- Harry Potter: The Final Chapter' airs July 10th, 8PM ET and 11PM ET on CNN.
