Percy Jackson is a character in a series, not an actor. The actor who played Percy Jackson was called Logan Lerman and he didn't play Harry Potter and wasn't in any of the Harry Potter movies.
Daniel Radcliffe, who is three years older and looks nothing like Logan Lerman, plays Harry Potter.
Harry Potter is played by Daniel Radcliffe Percy Jackson is played by Logan Lerman
He has never been in a harry potter film you may be thinking of percy jackson and the lightening thief in which he played hades god of the underworld
He plays Percy Weasley in the Harry Potter movies. :o)
They call him Perfect Percy as a play on him being a prefect who is supposedly good at everything.
