Revealing mistake: Dave is racing with the Italians, and the Italian puts his pump in Dave's spokes. In the middle of the bike falling over, you see a horizontal beige object with duct tape on it for a couple of frames, where you should see Dave.
Revealing mistake: In the scene where Brian Clough is at home you can see double glazed upvc windows, even though they were not around until the 1990s.
Revealing mistake: When Ali is in the rain on the pay phone at the motel it is a modern phone, not from the era they were trying to portray.
Revealing mistake: In most of the scenes of the film, the famous filly is impersonated by a colt.
Revealing mistake: Throughout the racing shots of the movie, the close up shots of the fans in the stands show the same people used multiple times as evident by them wearing the same clothes, poses, etc.
Revealing mistake: When Joe drives Camille on his bike, for a brief moment if you look closely a stuntman is driving for him.
Revealing mistake: The tapered half of the baseball bat was leaning against the coffee table at about a 60° angle, but after Dave said, "The bat?" the camera showed it sticking straight up from (perpendicular to) the floor. Dave's lower body is then shown walking past the bat (which reaches to his waist) and stopping, at which point the bat fades into his leg until it is almost invisible. The next view of the bat shows it leaning against the coffee table again, but the coffee table is closer to the couch. (00:09:08)
Revealing mistake: The reaction of the jogger being hit by Clark's bat is way too late.
Revealing mistake: When the tiles pop off the wall near the beginning, each pops off right in the middle. The nozzles squirting out the water are obvious.
Revealing mistake: The position of the lamp (upright or tilted) to the left of the screen varies, and the way the light is cast on the wall above and below the lampshade is not realistic. For example, when the upper part of the lampshade is angled away from the headboard, the light projects below the lampshade shorter toward the left of the screen, not elongated. (00:01:00 - 00:03:00)
Revealing mistake: During the Unsolved Mysteries scene, a man is about to play solitaire. Look at the screen, though. It's already dragging cards around.
Revealing mistake: In the closeups the boy is holding a large leaf of seaweed to offer the stallion. But in the long shots at the waterfront he extends an empty hand with no seaweed visible.
Revealing mistake: When Kathy Ireland is trying out, watch one shot from the side and you can tell by body type it's a guy in a wig kicking the ball.
Revealing mistake: During the last Race (the Agua Caliente), Phar Lap's hoof was re-opening from a crack earlier in the movie. When they show the close up of the leg/hoof during the race in slow motion, the "blood stain" keeps moving around on the leg wrap and hoof area.
Revealing mistake: In the opening montage, the article "Rucker Park today - The streetball Mecca" is also the rightmost column of the entirely diff different publication that comes in the following shot. (00:02:25)
Revealing mistake: When Capt Knauer aims the gun at Crewe after the game it shows the barrel with a plug and a hole too small for an actual bullet to come out of.
Revealing mistake: When Velvet and Mi are talking to the jockey in the pub, there is a blackboard behind him listing the menu. However, all the writing is backwards. The film negative apparently got flipped, in this print at least, resulting in a reversed image. This is the only scene where reversed lettering is seen.
Revealing mistake: In the fight against Apollo, Rocky's last punch of the second round conspicuously misses by a mile, but Apollo nonetheless acts like he has been punched, and there is a punch sound effect as well.
Revealing mistake: When Terrible Tommy has Rosa in an airplane spin her hair suddenly gets thicker and her legs get thicker, indicating this is Rosa's stunt double.
Revealing mistake: In the scene at the 1988 Monaco Grand Prix, the shot on board Senna's car is taken from qualifying, not the race. This can be shown in the shot after Senna hits the wall, as no on board camera is visible.
