The author argues that actor Johnny Depp has multiple personality disorder (MPD) based on research into Depp's personality and career. The author believes Depp's ability to portray diverse characters is evidence of MPD, which can be caused by trauma. Depp's comments about struggling to exit roles suggest his personalities become integrated with the characters he plays. However, the author suggests Depp's MPD may be subsiding since having a daughter, which has led to less distinctive, less successful recent roles.
