Judd Apatow is such an ubiquitous figure in comedy -- as a producer, director, and writer -- that it's hard to believe he's actually not associated with certain films. He had nothing to do with "I Love You, Man" or "This Is the End," even though those films star actors from his comic stable and center on the bromantic relationships that have become his trademark.

His new film "Trainwreck," opening July 17, marks a departure for Apatow; it's the first movie he's directed that he didn't write (Amy Schumer stars in, and also cowrote, the romantic comedy). In honor of his new movie, we've ranked and filed 19 Apatow films -- those he either wrote and directed or produced -- that you need to see.
