BREAKING. Larry King returns to CNN International for a Larry King Harry Potter TV special as Warner works its synergy magic.

Larry King is returning to CNN International (DStv 401) for a once-off Larry King Harry Potter TV special that will be seen in South Africa on Monday 11 July (no South African broadcast times available yet, although I have asked) ahead of the movie release of Harry Potter and the Deathly Hallows: Part II on Friday 15 July worldwide.

Larry King will interview Daniel Radcliffe, Emma Watson, Rupert Grint, Tom Felton, Helena Bonham Carter and Robbie Coltrane. Never-before-seen footage from the upcoming final installment in the Harry Potter saga as well as a behind-the-scenes look at the making of the film will be included in the special.

The Larry King Harry Potter TV special is corporate synergy at work. The film is of course distributed by Warner Bros. Pictures and CNN International is owned by Turner Broadcasting System, which is a Time Warner company.

In the TV special, according to CNN, Daniel Radcliffe calls the final Harry Potter film ''a hell of a movie'' and tells Larry King that he ''wept like a child on that last day'' of filming. Wendy Walker, the longtime executive producer of Larry King Live is the executive producer of this Larry King TV special as well.
