Visible crew/equipment: When Hughes is flying the new and faster airplane, you can see the filming crew reflected in the side of the plane. You can see it at full speed but you can see it better if you slow playback down a bit.

Factual error: While in the air shooting scenes for Hell's Angels, a camera mounted on a wing breaks and film flies out. The film is brown in color, the hue of undeveloped color film, and Hell's Angels was obviously filmed in black and white. The film should've been grey or blue as this is the color of undeveloped black and white film.

Continuity: After Noah Dietrich introduces himself for the first time, the shot changes and everything to the right disappears.

Continuity: When Howard Hughes cries out "Oklahoma," he passes behind Dietrich and then in the wide shot he is behind him again, repeating the movement.

Factual error: Some of the glasses in the film are too thin and modern to belong to the time period, such as the ones that Robert Gross wears. As well, his lenses, as well as those of Senator Brewster, reflect light with the distinctive iridescent green/purple of non-reflective coating, which was not available back then.

Factual error: In the 1940ish Connecticut scenes of the Hepburn family, one member was taking movies with a Bolex reflex movie camera not manufactured until the late 1950s.
