Mad Dogs and Servicemen - S3-E13
Factual error: While Radar's lying in bed, Margaret reads a letter to him which was written by Wanda McCandless, and in the letter Wanda mentions that her favorite songs are "Pretty Thing..." by Bo Diddley, and "Oh, The Wayward Wind..." by Gogi Grant, but the problem is these songs were written and recorded in 1955 and 1956, years after the Korean War was already over in 1953.
Mad Dogs and Servicemen - S3-E13
Visible crew/equipment: As the medics take a stretcher off The Bus, and then Hawkeye goes into The Bus, the shadow of the recording equipment boom plays across them.
Continuity mistake: In some shots the Spam lamb has mashed potato eyes and a carrot mouth, in others it has green grape eyes and no obvious mouth, and it keeps changing. (00:23:10)
Audio problem: At the end of the show, when Trapper is playing his instrument, the music does not match the movements of his hand.
Visible crew/equipment: While the Greek shipment of food is being brought into the mess tent, when the cook carrying the lamb walks behind the table, the edge of the tent set can be seen at the top right corner of the screen.
Continuity mistake: In the shot where Hawkeye presents the Spam lamb to Henry, he sets it down, and Henry asks him what it is. Behind Henry, you can see Hawkeye's shadow - and see his lips mouth the word "A Spam lamb". The camera then changes to a close-up of Hawkeye, saying "A Spam lamb".
Visible crew/equipment: While Trapper and Hawkeye are already in Henry's office Radar and Henry walk in, and just as Henry says, "Everything in this country disappears except me," the shadow of the boom mic can be seen moving across the wall at the top right side of the screen.
Continuity mistake: When Radar goes to get the lamb, he pulls out a hypo to put the lamb to sleep for shipping. When the shot cuts to the lamb, you can see both of Radar's hands on the lamb's face; no hypo in sight.
Revealing mistake: The sound of crew making an explosion with their mouth as a cue can be heard just before the actual audio of an explosion plays.
Continuity mistake: When Margaret asks Frank for cash to help her sister get an apartment, he asks about her father leaving her anything, implying that her father is dead. Later on, we see her father when he comes to visit her in another episode.
Continuity mistake: First, Radar is seen drumming on his tin cans with bare hands. After cut, when the hula girl appears, without interruption of the drum pattern, he suddenly is holding some sort of drumsticks. (00:15:00)
Continuity mistake: When Henry, Trapper, and Hawkeye get into the jeep with Radar notice the style of jeep and its number is 16930382, but when they're driving to the chopper pad the style differs - things such as hood, antenna, etc, and its number is 11172419. Then when the chopper takes off the jeep's style is back to the original jeep they were in.
Visible crew/equipment: At the chopper pad, as the scene plays out, reflections of the lighting rigs can be on the chopper canopy.
Continuity mistake: As Henry watches the chopper fly off, his back is to Radar's jeep. After he orders back to camp, Henry is suddenly standing with his right side to the jeep without having turned.
Audio problem: As Hawkeye and Trapper get into the chopper, you hear the engine powering up, and the blades slicing the air, but the blades aren't moving at all.
Other mistake: When Trapper and Hawkeye are driving along, you can see two points of light on the steering wheel. The lights are from from the filming illumination panels.
Other mistake: When Trapper and Hawkeye make the right turn after Trapper tries to use the restroom, you see that Trapper avoids the left side of the road just after the turn. This is to avoid the explosive charge set in the ground used to simulate a mortar round exploding.
Audio problem: At the end when Borelli is getting ready to take off, in the close ups you can see the main rotor blades starting to turn, getting ready to fly. But the sound suggests that the rotors and engine are already at full power.
Revealing mistake: In the swamp during the movie, Frank comes up and talks to Igor, who is running the projector. Although there is a film running, there is no film on either the supply or take-up reels.
Factual error: In the beginning, Hawkeye says that the patient was full of shrapnel from a claymore. M*A*S*H was set in the early 50's, and the M18 Claymore was only in the development stages in 1952, and not accepted and battle used until Vietnam in 1961.
Answer: Even an Army field hospital would have SOME weapons for self-defense if the enemy attacked. What's meant is that it's not a combat outfit, and therefore wouldn't have enough weapons to actually attack anyone. (It's also mentioned a few times that the Officer of the Watch is supposed to carry a pistol at all times, but Hawkeye refuses to do it when he's in charge and Colonels Blake and Potter don't enforce the rule).
