Daniel Radcliffe is telling fans that the next installment of the Harry Potter films, "Half Blood Prince," will be the funniest of them all.
Director David Yates says it's the "sex, drugs, and rock and roll" of the Potter books, with massive making-out sessions to occur for several characters as they come of age.
"It's the 'American Graffiti' for this set," Yates said. "I'm looking forward to developing the relationship between Ron and Hermione, and Ron and Lavender. There's a nice triangle there." Is that the kind of triangle I'm thinking of?
