While filming Pies and Guys (1958), Moe is holding a pie in his left hand. As he prepares to hit Larry with it, he's holding the pie in both hands.
When studio head Harry Cohn is watching Stooge shorts in a screening room, one shows a copyright of 1941, but the next time frame given is 1936.
Curly Howard did not suffer his career ending stroke during the filming of a scene of Half-Wits Holiday (1947). It happened while he was offstage waiting for the scene to begin. He didn't respond when called, and Moe found him with his head slumped to his chest, unable to speak.
The film implies that Curly Howard was confined to a wheelchair for the rest of his life. In truth, he did recover to a point from his career-ending stroke, and even married (again) and had a daughter. He can be seen making an unbilled cameo appearance as a train passenger in Hold That Lion! (1947). He is noticeably thinner and had a full head of hair. His health did deteriorate after 1949, and he died in 1952.
After The Three Stooges retired, Moe Howard is shown delivering lunch to Columbia President Harry Cohn and later taking Cohn's Cadillac out to get washed, all in order to make some extra money. That never happened, as Moe had made some very astute investments over the years and by the time he retired was quite well off.
The Three Stooges were shown filming Disorder in the Court (1936) when they learned of Ted Healy's death. In reality, this particular short subject was released in 1936, and Healy died in 1937. Also, the Stooges did not encounter Healy at a nightclub the night he died. Moe found about his death via a phone call from a reporter when the Stooges were in New York.
Ted Healy's death is described simply as an unfortunate coincidence, presumably a heart attack resulting from celebrating the birth of his child. In fact Ted Healy was beaten to death when leaving the Trocadero nightclub. The "mystery" was never officially solved, although star Wallace Beery and Cubby Broccoli (later producer of the James Bond films) admit to fighting with Healy that night.
Curly Howard actually joined The Three Stooges while they were still part of Ted Healy's act, and it was in fact Healy--not, as the movie says, Moe Howard--who suggested that Curly Howard shave his head bald. Healy felt that Curly did not look funny enough with his full head of hair and waxed handlebar mustache.
During the first Steadicam shot of Larry Fine, Curly Howard and Moe Howard at the train station, a Sydney City Rail automated ticket machine can be seen in the background behind the potted plants. These ticket machines were not created until the late 1980s.
In the scene filmed at Sydney Central station, as they walk to board the train, you can clearly see a 1980s built Inter city electric train.
Modern glass sliding doors can be seen at the front of the Seattle Central Station.
The film Soup to Nuts (1930) is mentioned as a 20th Century-Fox production. 20th Century-Fox was not created until five years after "Soup to Nuts" was released. The film was produced and released by Fox Film Corporation.
When The Three Stooges first drive onto the Columbia Pictures lot, a line appears onscreen that says, "Columbia Pictures, 1934". However, several cars from the late 1930s and early 1940s can be seen parked on the lot or driving by.
At the premiere of Soup to Nuts (1930) at the State Theatre, an outdoor close-up of Moe reveals a blue neon "Allianz" logo in the background, at the top right corner of the screen. This was the Allianz building in Sydney.
Contrary to what the movie asserts, Moe Howard was very shrewd with money. Through wise investments, he had accumulated a small fortune in the late 1950s and actually considered retiring.
Contrary to what the film shows, Moe Howard was very broken up when he learned of Ted Healy's death and actually cried, something he was not known for doing very often.
On the radio, it says that Shemp Howard has died aged 59. In actual fact, Shemp was aged 60 when he died.
Contrary to what's shown in the film, it was Moe Howard who felt that The Three Stooges' routines worked better in shorts rather than features. In fact, in 1935 he rejected Columbia's proposal to star them in a full-length feature.
Shemp Howard is portrayed as being anxious when traveling by train, but sits relaxed in the back seat of a car as they drive along the coast. This was the opposite of how Shemp was in real life. He was always anxious when riding in a car for too long and preferred to travel by train.
