If there was ever an actor to have benefited the most from Judd Apatow, most may think of Seth Rogen or possibly Jason Segel. Given his history with both actors in the cult classic Freaks and Geeks, both actors have indeed benefited greatly from Apatow. But neither of them have benefited the most. He simply turned two newcomers to the industry into mainstream stars. The one actor who has – is Paul Rudd. An actor who has been in the industry prior to Apatow going big time, now is his almost go-to guy.
