Mobile Army Surgical Hospital. M*A*S*H had a runtime as long as its expanded name, and naturally not every cast member could make it in every episode - or even every season. So, who, in this broad roster, was there for the very beginning and ultimate end? Right away, it\u2019s easy to name Alan Alda and Loretta Swit, but is there more to it than that? M*A*S*H ran for 11 seasons encapsulating 256 episodes from September 17, 1972, to February 28, 1983. Alda can boast of appearing in every single of those two-and-a-half hundred entries. Swit comes in close with 239, but she is not the only one.

Fans also note that the character of Father Mulcahy was in both the first and last episodes. However, this does not extend to the actors, plural, who played him, since Dennis Christopher took over for George Morgan from the pilot. It all goes down the drain The M*A*S*H finale \/ YouTube screenshot Of the hundreds of M*A*S*H episodes to air, Alda wrote 31 of them, and one of those included the finale. Alda first started directing for the show back in season two with the episode \u201cMail Call.\u201d Though he had a decent amount of experience by the time he worked on the finale, it was full of unexpected hiccups.

The crew ended up filming the inferno, which added to the episode\u2019s runtime already set at 90 minutes. MeTV also writes that so many people were gripped by the show that they stayed glued to their TVs until it ended; only then did they, as one, rush to the bathrooms. Reportedly, everyone flushing at once caused a pressure drop that in turn brought water from the Catskills to New York. That\u2019s one way for a show to be remembered!
