Okay, so the two stars didn’t actually appear on yesterday’s Late Night. But Fallon did hilarious impressions of each one dissing the other’s movie (check out the clip above).

Pattinson: “It should be called Harry Potter and the Half-Ass Film.”
Radcliffe: “What do vampires do best? Suck.”

I’m going to declare Radcliffe the winner on the strength of his “Call Super Cuts-icus” spell. What about you, PopWatchers? Who wins the imaginary insult war?
