Harry Morgan had trouble finding the right personality for Col. Potter when he joined M*A*S*H
He wanted to make Potter ''more wacky'' and keep an iconic piece of Henry Blake's costume.

Season four was a time of change for M*A*S*H. The real Korean War lasted three years, so perhaps it was unsurprising that the television show would have to get creative after the same amount of time. The dramedy kept things fresh by shaking up the cast. Henry Blake (McLean Stevenson) and Trapper John (Wayne Rogers) left the series. Enter Mike Farrell as B.J. and Harry Morgan as Col. Potter.
The one-hour, two-part "Welcome to Korea" introduced B.J. Hunnicutt to kick off the fourth season. "Chain of Command" welcomed Sherman T. Potter to the 4077th as its new commanding officer.
In August 1975, a syndicated UPI column introduced Morgan as the newest M*A*S*H cast member to the newspaper readers of America. "Morgan is low-key. He exudes warmth and dry humor," the writer observed. "His soft sell, unobtrusive quality probably is the reason he holds the record for most series as a star performer."
That's right — at that point in television history, Morgan had starred as a lead in more TV shows than any other actor. That list of series on his resume included December Bride, Pete and Gladys, The Richard Boone Show, Kentucky Jones, Dragnet, The D.A., and Hec Ramsey… all packed into the span of 20 years. The actor born Harry Bratsberg was no stranger to replacing beloved characters, either. He had done just that as Sgt. Friday's partner in the 1967 Dragnet reboot.
Pete and Gladys — in which Morgan played straight-man husband Pete Porter to scatterbrained wife Gladys Porter (Cara Williams) — came the easiest to him.
"My favorite was Pete in Pete and Gladys because I just played myself," Morgan admitted to the UPI journalist.
"Until now Morgan has found it easy to slip into his characterizations," the writer noted. "But he's having trouble fitting himself inside the skin of Colonel Potter." What was the obstacle? For starters, the still-looming shadow of McLean Stevenson hung over the Morgan.
Morgan even considered using an iconic piece of Henry Blake's costume.
"I wanted to keep that fish hook hat he wore," Morgan admitted, "but McLean took it with it him."
"I'd like to make the colonel a little more wacky," he added. "It's taking me time to find the right niche for this guy."
Morgan explained that he preferred comedy to drama, but he appreciated that M*A*S*H was not "typical fluffy situation comedy," perhaps a slight dig at his roots on December Bride and Pete and Gladys — or, at least, an admission that he was ready to try something different.
To his credit, he nailed the persona of Colonel Potter. Without making him "wacky" or wearing a leftover fishing hat.

Then after M*A*S*H there was AfterMASH, Blacke's Magic and You Can't Take It with You. And he didn't spend more than one season between any of those series from 1954-1988. In addition, he guested on several series in between those, such as Alfred Hitchcock Presents, The Partridge Family and the 1980s Twilight Zone.
What does one have to do with the other? Are you saying if the Korean War lasted another year, they would have had to get creative in the fifth season?
"The dramedy kept things fresh by shaking up the cast. Henry Blake (McLean Stevenson) and Trapper John (Wayne Rogers) left the series."
It wasn't a "dramedy" at that point. The actors left on their own, the producers didn't fire them to shake things up.
"The one-hour, two-part "Welcome to Korea..."
It's either a one-hour broadcast or a two-part episode. Can't be both at the same time.
I began liking Harry Morgan as Bill Gannon on "Dragnet" and the BJ character of a loving and faithful (for the most part!) husband and father just improved MASH so much for me! I also liked it better when Hawkeye and Margaret grew in their friendship/romance. MASH was so much better at the end! Even Klinger found his soul mate in Soon Lee!!!
There is no emotional attachment to a woman you bought for 2 dollars or a can of spam.
Go down to your local VFW or Legion hall, if the guys will talk about it truthfully the far majority
indulged themselves with the women "over there". Why do you think the army shows those
films over and over again about VD, with disgusting and graphic examples of advanced cases,
diseased members etc. Everyone here reading this whose father, uncles, brothers, sons served
overseas, the reality is most of them indulged too. But that's their business, as are the intimate details of combat as when your friend buys it, you don't share his death with outsiders, that's just for your squad buddies and "outsiders" can never be a part of it. They might share some of it
with the wife, after waking up screaming in the middle of the night and weeping in her arms.
Sorry to go off on a tangent here.
