Continuity: Near the beginning of the film where Howard Hughes flight tests the silver monoplane (the H-1), the close up shots show an open cockpit while the longer shots show a closed cockpit.

Continuity: 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: While having dinner at Kate's house, Howard Hughes yells out a comment about money, and after that the roses on the table have totally changed position from before.

Continuity: 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.

Continuity: Hughes asks Ava Gardner "Feel like going to Paris?", then the guy behind her disappears.

Revealing: Early in the film, when Hughes and another guy are walking past one of the replica WW1 aircraft used for the "Hell's Angel" scenes, you can see the ends of the cylinders of the modern air cooled engines they used to power it. The original aircraft (SE-5A) used a water cooled V8 which wouldn't have been visible.

Continuity: Immediately after the screening of "Hell's Angels", Noah Dietrich (seated right behind Hughes) begins applauding, and others join in. In the next shot of Dietrich, he begins applauding again.

Audio problem: Towards the end of the scene where L.B. Mayer is dismissing Howard's request for some cameras, the audio does not match at all with the way his lips are moving.

Revealing: During the filming of 'Hell's Angels' Howard gets the idea to build a single wing mono plane. He and another take an axe and smash the support holding up the upper wing. If you notice the upper wing is already broken, hinged and a very poor covering has been laid over the joint. It is very obvious and noticeable in a few shots leading up to this.

Deliberate "mistake": 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.

Continuity: In the final scene of the movie, as Hughes walks forward with Gardner, they stop walking in the head on shot. When the shot changes to a side profile, they are still walking forward.

Continuity: When Hughes is dining with Domergue and Juan Trippe is leaving the place, the spoon on the sundae keeps moving around.

Factual error: When Hughes flies the open cockpit H-1 at over 350mph he isn't wearing goggles. There isn't a sign of any wind at all in the cockpit. Even with a windscreen, the wind would cause your eyes to water well before 350mph.

Continuity: When HH's plane is rampaging the houses, a couple of white mugs in a kitchen fall down twice.

Continuity: When Howard asks L.B. Mayer to loan two cameras, we first see Mayer and his associates from Howard's viewpoint as he is approaching them, and Mayer is standing with the bar on his left. In the next shot Howard greets him, and the men in the group have changed places, with Mayer now facing the other direction and now the bar is on his right.

Continuity: Hughes leaves Ava and goes, hat in hand, to talk with his two pals. Suddenly he is seen with his hat on. Less than half a second to put on a hat without moving your arm IS fast.

Continuity: Inside the projection room, Hughes hand the photo of an actress with a sketch of the Hercules behind. The sketch is sideways as we can see when the guy is flipping the photo. But when the angle changes finishing his movement, the sketch is seen straight.

Continuity: When Hughes is asking Ava about going to Paris, 2 guys with blue suits pass behind three times.

Continuity: During lunch with the Senator, the vegetables and potatoes on Hughes' fish change between the first and second shot.

Continuity: Before Flynn is thrown the paper ball, a couple passes behind him and disappears in the next shot.
