What does mark Radcliffe do for the Harry Potter movies?

Mark Radcliffe is not involved in the Harry Potter movies. He is a British radio and television presenter, known for his work on shows like "The Radio 1 Breakfast Show" and "The Mark Radcliffe Show."

There seems to be some confusion, as he is not a film director, producer, or involved in any way with the Harry Potter franchise. Perhaps you are thinking of someone else?
