Factual error: The opening scene of the film, with a woman singing "For Your Country and My Country" at a bond rally, is supposedly set in 1917, but her hair and clothing are pure 1940's: calf-length skirt and curled shoulder-length hair, neither of which was acceptable attire for a lady in 1917.
This Is the Army (1943)
1 factual error
Directed by: Michael Curtiz
Starring: Joan Leslie, Alan Hale, George Tobias, George Murphy
Deliberate mistake: During the early rehearsals for "Yip Yip Yaphank", a group of men are around the piano singing "God Bless America", and we hear the following lyrics: "Stand beside her/And guide her/TO THE RIGHT/With a light from above". This is NOT an error; I'm guessing that those were the actual lyrics of the rough draft, with the capitalized line above changed to the present "Through the night/With a light." at a later date.

Sgt. McGee: What's the matter with you Twardofsky? Don't you like our early morning calisthenics?
Pvt. Twardofsky: Well, I didn't like 'em at first.
Sgt. McGee: Oh, you didn't like 'em at first. How do you like 'em now?
Pvt. Twardofsky: I'm still on first.
Trivia: Even though George Murphy plays Ronald Reagan's father in the movie, he was only 9 years older than Reagan.
