"Henry" Morgan (*) had a prolific film career during the 1940s and 1950s, which is often overlooked due to his high-profile recognition as a television actor (DECEMBER BRIDE, PETE & GLADYS, DRAGNET and M*A*S*H). Supporting roles, often as the leading man's buddy, in a long list of popular films.
I highly recommend THE OX-BOW INCIDENT (1943), with Henry Fonda, Jane Darwell and Anthony Quinn. Other recommended credits of Morgan's to see are HIGH NOON (1952), BEND OF THE RIVER (1952), THE GLENN MILLER STORY (1953) and INHERIT THE WIND (1960).
* Trivia - He changed his name from "Henry" to "Harry" in the mid-1950s. Henry Morgan was a NY magazine/newspaper columnist, popular as a panelist on TV game shows like TO TELL THE TRUTH and WHAT'S MY LINE? To avoid name confusion, particularly after landing a costarring role on the sitcom DECEMBER BRIDE, Morgan (the actor) changed his name to "Harry."
Trivia - In the M*A*S*H episode "The Moon Is Not Blue," the camp is watching STATE FAIR (1945), which costarred "Henry" Morgan.
Stooge-connections - He costarred as a gangster in OUTSIDE THE WALL (1950), which had Joe Besser in a small, supporting role. And, Jack Webb and Harry appeared in the U.S. Govt. short STAR SPANGLED SALESMAN (1968), which also featured Moe, Larry and Curly Joe.
