Was used as a stand-in or "line feeder" for Harrison Ford during the casting process for Blade Runner (1982). Paull appears briefly in a "movie within a movie" in Ensign Pulver (1964). He is not listed in the "Ensign Pulver" cast credits, but he is credited on-screen in "Young Dr. Jekyll Meets Frankenstein", a movie being watched by the ship's crew. "Young Dr. Jekyll etc." was fabricated using some new shots of Paull and other actors, inserted into old footage from The Walking Dead (1936), an actual Warner Brothers release that starred Boris Karloff and Edmund Gwenn, who also are credited on screen. Paull's credit reads "And introducing Morgan Paull as "Young Dr. Jekyll". Ex-son-in-law of Marcella Martin. Ex-brother-in-law of Martin Huston.
