One day during shooting when the "Mexican Forces" (reenactors from across the USA) were forming in the field, a B-52 from the nearby USAF base in San Antonio "buzzed the deck" to have a look at the movie being made. What its crew thought of hundreds of "Soldados" happily waving, no one has ever found out.
First Alamo movie to depict Colonel Travis with a double barrel shotgun.
Despite being less than 1 hour long, this is the most historically accurate film made about the Alamo to this very day.
The 2021 book "Forget the Alamo" comments that this film is "rife with inaccuracies. Bowie is seen up and around, even giving a stirring speech when he was known to be bedridden. Crockett goes down fighting. The wrong flag flew over the Alamo... There were no significant Tejano characters anywhere in the film. The minor Tejano characters that did appear were wholly subservient." A scene involving a "pretty senorita" and a drunken Kentuckian was cut. "None of it mattered. The IMAX theater at San Antonio's Rivercenter Mall shows the film to this day."
