Corrected entry: When Hughes is being shown the model for the Constellation plane he is quoted $450,000 per aircraft. He then says "that's $18 million for the first four". Four times $450,000 is only $1.8 million.
Corrected entry: The fuel gauge for the speed test is grossly exaggerated for effect. They just got done telling him that there is minimal fuel for weight considerations. Just after takeoff, it reads about 40, which is half full. After the first run it's down around 30. Going into the third run it's near 10. Given the H-1's range of 2,490 miles, even pushing the engine to it's limits shouldn't drain that much fuel that quickly nor should the engine stall at 10. (01:44:40 - 01:46:20)
Corrected entry: When Howard and Katherine Hepburn are eating dinner, Errol Flynn comes by to talk. The waiter delivers Howard's dinner, a steak, twelve peas and a jar of milk with the cap on. Errol reaches over a takes one of the peas off of Howard's plate. In slow motion we can see that Errol indeed removes a pea from his plate. Howard then looks at his plate. When paused we can count that there still twelve peas on the plate. There should only be eleven peas. Howard then pushes his plate away from him. A few shots later the peas have moved position and then there are only ten peas on the plate. (00:33:40)
Corrected entry: When Howard is watching 'Hell's Angels' footage in his private screening room, he holds his hands up in front of the projection and the image of several planes from the footage can be seen on his hands. The corresponding long shot shows his hands, illuminated by the projection, yet there are no corresponding shadows of his hands on the screen.
Corrected entry: In one scene Howard Hughes is watching "Hell's Angels" alone in a private screening room. He puts his hands up, one on each side of his head and at eye-level, and looks at the images from the film being projected onto them. Meanwhile, the back of his head, directly between the hands, is in deep shadow.
Corrected entry: After talking about the plane orders and plans with Juan Trippe, Howard goes to the bathroom to wash his hands. Notice the dish he takes the soap out of. From the shot to shot above the sink, the soap dish on the right hand side of the sink constantly changes position and the interior of the soap dish is sometimes brown and sometimes aluminum. (01:23:20)
Corrected entry: When Hughes and Harlow are being assaulted by the paparazzi flashes at the premiere of "Hell's Angels", the discarded "flash bulbs" they step on are badly simulated by regular screw-in 60-watt-type light bulbs strewn about the walk. The screw-in base and distinctive shape and color (white) is easily identified (there are close-ups of them). Look for the GE logo.
Corrected entry: In the movie, TWA (Transcontinental and Western Air) gets renamed Trans World Airlines, but that didn't really happen until 1950.
Corrected entry: As Hughes cuts through the "beet" field in his emergency landing, the splatters of red were entirely inappropriate. Beets grow under the ground. The colors of the splattered, wet stuff hitting the plane were intense green (OK) and bright red like tomatoes (not OK). Had he really been grinding up hardy tubers like beets, he would be spitting up mostly dry dirt. The true color from beets would be altogether different (beet red is more purple than orange-red), it looked more like he skimmed a tomato field.
Corrected entry: When Hughes is flying with Katharine Hepburn, he hands over control of the aircraft to her. When they approach a hill she asks him what to do and he tells her to pull back on the stick. She does this, without touching the throttle, and the aircraft climbs. The problem is, that this would also cause it to lose speed, stall and probably crash.
Corrected entry: After Hughes has flown 353mph in the H-1, it's claimed that he's the fastest man in the world. That's not true - the Italians had set a world air speed record of over 440mph in 1934. Surely everybody involved would have aware of this? Hughes actually set a landplane speed record, not a world speed record.
Corrected entry: When they are increasing the speed of the Spruce Goose preceding takeoff, the flight engineer calls out the speed in miles per hour. When the camera shows the vibrating gauge it is calibrated in knots.
Corrected entry: Howard makes an emergency landing in a field of rhubarb. In the following scene, however, he tells Kate Hepburn that the stains on his clothes came from beet juice.
