Other mistake: When Reinaldo first meets Lezaro Lima after winning "First Honorable Mention" for the National Book contest, Lezaro tells Reinaldo he can read any five books he wants. Lezaro names titles of books he'd like Reinaldo to read. The subtitle in English on the U.S. region DVD misspells Robert Louis Stevenson, spelling his middle name "Lewis". (00:32:05)
Other mistake: Either there was or wasn't a 5-year contract from the onset. At first, Sherwood told Bob, "It's just a pilot episode. If we get picked up for a series." Narrator Barry Williams said his agent called to tell him "the network picked up the Brady Bunch for a full season." Season One ended but Sherwood didn't call "until the last minute" to tell the cast they "would be coming back to a second season." Later, Sherwood told Bob that he knew when he did the pilot that he signed a 5-year contract. (00:05:50 - 00:21:40)
Suggested correction: Those two things are not mutually exclusive and that's not how it works in the television industry. Actors usually have to sign a test option agreement with the studio prior to the pilot being picked up (sometimes even before auditioning). This ensures the studio that the actor is committed to the project long term should the pilot be picked up, but signing the contract agreement doesn't guarantee the pilot will be picked up. A 5-year test option agreement seems pretty standard.
I'm aware of such contracts - and surely Florence Henderson would have also been required to sign a five-year agreement, but there (conveniently) was no mention of this.
Other mistake: When Erin starts working on the case, her youngest daughter is supposedly 10 months old. Later on in the film, Erin says she's been working on the case for 18 months, which would make her daughter more than 2 1/2 years old, but the actress playing the daughter is at least a year too young for that. Also, Katie and Matthew don't age at all over those 18 months.
Other mistake: In the courtroom scene, when Chief Sunday tells Brashear to stand up, the tenders go to help him up without question, and when Captain Hanks overrides him, saying that he has to stand up himself, even they look confused and surprised. They wouldn't be just some random enlisted sailors doing this, they have been trained in being a tender, and would reasonably know what the policies are. (01:56:50)
Other mistake: When Potiphar is buying the horse, Zuleika calls him Joseph when calling him to come fan her before they then ask him for his name. (00:30:00)
