Factual error: Jockeys did not wear goggles and their skullcaps did not have chinstraps in the 1930's. Protective equipment for jockeys was practically non-existent during Seabiscuit's racing days. (00:28:10)
Factual error: In the scene where Red is with the Mexican girl and half the screen goes dark to show that he's blind in one eye, it should actually be less than half the screen. The visual fields of the eyes overlap to allow for depth perception. You can see for yourself by putting a pencil vertically at the tip of your nose and closing one eye - if you look straight ahead you can still see things on the other side of the pencil. Red should be able to see slightly more than half of what's in front of him. (00:32:45)
Factual error: In the scene where Red Pollard is walking hots, he is leading the horse around on a mechanical walker which did not exist at the time. (00:41:40)
Factual error: In the scene where Seabiscuit is weaned from his mother, the narrator says that he was six months old at the time. However, the foal used in the movie is less than one month old. (00:43:30)
Factual error: There is a scene at Saratoga where the grandstand is viewed from the backstretch. In the 30's the grandstand was not that large. Since then, there have been several additions to the grandstand. You can plainly see the new clubhouse (the white area on the left) which was just added recently. In fact this particular view should have shown the "Wilson Mile" chute which is no longer in existence but was in the 30's. (00:48:25)
Factual error: The flat top inside rail at Santa Anita racetrack is a new style safety rail. (00:59:50)
Factual error: When Charles gives Red a $20 advance he hands over a modern bill. (01:03:40)
Factual error: When they are heading east to race with War Admiral, there is a scene at the Los Angeles Union Station. This is in 1938; the station was not opened until the following year. (01:20:00)
Factual error: In the scene where the Seabiscuit Special is headed East, they make a stop in Albuquerque. If you look closely, in one shot there are palm trees in the background. There are no palm trees in the vicinity of the Albuquerque train station. (01:21:10)
Factual error: The Pimlico race track has a modern electronic scoreboard. It's visible when we see the race course in the morning before the race starts as well as after the race. (01:35:00 - 01:42:00)
Factual error: In the shot where Pimlico racetrack is shown and the dateline shows November 1, 1938, the Maryland flag is upside down. The black and gold squares should be at the inside top and they are not. (01:35:10)
Factual error: In the shot with Howard and Red riding in the thirties vintage Buick, Howard flicks on the car radio, and the sound is instant. In those days, car radios were vacuum tube type, and needed several seconds to warm up before you would hear anything. (01:57:35)
Factual error: During the end credits, some newspaper typesetting material is shown. The type should be shown in reverse with the letters backwards. However, the type is not reversed and you can read the words. (02:07:50)
Factual error: In the shot of the infield at the Saratoga racetrack several Canada geese are shown landing. However, the calls inserted on the soundtrack are the quacks of mallard ducks not the honks of Canada geese.
Factual error: Many of the main characters are using modern-day binoculars (black, plastic) throughout the entire movie.
Factual error: Two men are trying to start a John Deere Model D tractor, which backfires, startling the horse. The wrong sound effect is used; it sounds like a V8 engine being turned over by an electric starter. The tractor's flywheel, on the left side, is shown stationary. Turning the flywheel by hand is the usual starting procedure for a JD tractor of '30s vintage. For over 40 years John Deere tractors used a two-cylinder engine, which make a distinctive popping exhaust sound. The movie is right on one thing, JD tractors could backfire.
Factual error: Pollard did not lose his sight in a fight, as the film suggests. He lost it when he was galloping a horse for exercise and a horse going in the opposite direction kicked up a clod of dirt that struck him at the base of skull and knocked out the cerebellum on his left lobe. (right side, left lobe).
Factual error: Statements are made in the movie that War Admiral was "almost 18 hands" tall, when in reality, War Admiral was only 15.3 hands tall. War Admiral's nickname was "the giant killer." Seabiscuit stood 15.2 hands tall. Both horses were considered very small as racehorses.
Factual error: When Red Pollard is showing the doctor his homemade brace, his bare leg shows no sign of having been nearly severed or undergoing multiple surgeries. There are no scars, atrophied muscles, or discoloration of any kind. In reality, Pollard's leg was permanently disfigured.
Factual error: Pollard never told Smith and Howard he was blind in one eye. He kept it a secret, presumably until the eye paled or his fame had dropped off and no one really cared any more if he was blind or not.
Answer: I have tried to look this up, and there is no record of Red's parents. Most likely they just died of old age.
