Continuity mistake: In the dining scene where Howard Hughes' girlfriend has a sundae sitting in front of her, the cherry which is on top of the sundae changes positions in several different shots. First, the stem is turned towards the left, a few shots later, it is turned towards the right, then left again. It also shows up in the bottom of the dish, then in the next shot, it is back on top of the sundae.
Continuity mistake: When Hughes and Odie are talking about mounting a camera on a biplane and removing one of the wings, the shots alternate between a back view of their heads and a front view of their faces. Odie's head position has no relationship to the one it had in the preceding angle in most of the cuts.
Question: The colors in this film are otherworldly, (almost like the colors in a black and white movie that has been artificially colorized) and could not have been natural or achieved with any net or filter. I'm fairly certain that there is no method of stylized pre-exposure, and digital colorization, while possible, would have been painstaking on such a grand scale. How did they accomplish it?
