I used to have a section here at my site about M*A*S*H bloopers. There were quite a few of them, mostly about continuity issues (such as Hawkeye mentioning a sister in one episode when otherwise he was an only child) with the occasional production error thrown in for good measure. I got rid of that section because there are plenty of other websites that track bloopers although I did keep this section on anachronisms.
I’ve also recently discussed several examples of scenes from M*A*S*H in which characters were supposed to be naked but the actors themselves weren’t. I find this sort of thing more interesting than, say, the fact that Henry’s wife was referred to as both Mildred and Lorraine. In my mind, anachronisms and other mistakes made during the production of M*A*S*H are goofs. Continuity errors within the series are bloopers. The terms don’t mean much and are nearly synonymous but they’re what I’ll be using going forward.
Every so often I’ll be pointing out specific goofs and I hope other M*A*S*H fans contribute goofs of their own.
There is a scene where you can see the sky and high line wires in the upper left hand corner of the swamp it’s the episode called “are you now, Margaret” its about half way through the episode during the discussion about Margaret being a spy
In Season 4, Episode 8, “Dear Mildred” – Two different horses are used. When BJ and Hawkeye are trying to lasso the horse the bridge of the nose has a wide strip of white. Then when Radar puts the rope around the horse it has a narrow white strip on the bridge. At the end, when Col. Potter rides off, the first horse is used again. Also, throughout the the episode they refer to the horse as ‘him’. In subsequent episodes, the horse’s name is Sophie and thus changed gender.
