At one point, Bowie pulls his famous knife out of the sheath and allows Crockett to examine it. When the camera cuts back to Bowie, his knife is back in its sheath, despite the fact that Crockett is still holding it.

During the final battle, one young Alamo defender kneels to reload his weapon. A man beside him is hit and falls onto his back. In a panic the young defender jumps into the unfinished well. There's a brief cut looking into the well showing him land before it cuts back to ground level as Mexican soldiers rush forward. That defender that originally fell on his back is now gone.

At 40:51, Micajah talks to Crockett at the palisade. The camera turns to an over-the-shoulder shot to Crockett, Micajah lowers his left hand from the palisade. As Micajah continues to speak, the camera cuts over to an over-the-shoulder from Crockett back to Micajah, his left hand is still propped up against the palisade.

During the final battle at the Alamo, the Alamo defenders begin to turn around the 18 pound cannon. The next scene is an overhead view of the Alamo compound and if you look to where the 18 pound cannon is located, Mexican soldiers can been seen already at that location pushing back the Texian defenders down the ramp. The next scene goes back to the Texians preparing to fire the cannon.

When Lt. Colonel Travis is departing from the house where he drops his son off, we see Joe, his slave, standing next to his horse. In the next shot, Joe is already mounted.

In an early scene, as two gentlemen watch Houston and Crockett talking, one gentleman remarks that just a year past, Houston and Crockett would've had their caps set on "the White House". The building was painted white and had occasionally been called that, but, in polite society, it was the President's Palace, the Presidential Mansion, or the President's House until the Theodore Roosevelt administration. (Officially, it was the Executive Mansion until TR changed the stationery.)

The the Final Battle, most of the Mexican soldiers look like they are waiting for a attack. In actuality, most of the Mexican Soldiers had been asleep or let their guard down when the Texians began their surprise attack.

Jim Bowie was supposedly shot several times in the head.

In March of 1836, Antonio Lopez de Santa Anna was about 42 years old. Emilio Echevarria, while his birth date is publicly unknown, is (visibly) significantly older, not close to resembling how Santa Anna looked at the time.

Davy Crockett was not wearing the hunting vest that he is shown, because the actual one is on display at the actual Alamo. Crockett's body was burned along with all but one of the defenders.

Contrary to the popular image, this movie accurately portrays the Alamo without its iconic bell-shaped facade atop the front wall of the church. That was added by the U.S. Army in 1850, 14 years after the battle. The John Wayne 1960 version made a half-hearted attempt to recreate the facade as it exists now, but in fact, the roof of the church was flat all the way across in 1836.

Unlike most depictions, which have Crockett killed at the battle on the Alamo, there is an account by a Mexican soldier (that was translated into English after several depictions were made) who recognized Crockett and saw him executed as a prisoner of war after the battle.

When Davy Crockett goes to shoot at Santa Ana, he only half-cocks his rifle. This acts like a safety and would prevent him from firing.

The shell defused by Travis is too large to have been fired by any of the Mexican guns.

The movie Alamo chapel is about 50 feet too deep into the compound. Look at the convento [correct spelling] wall at the Alamo plaza for confirmation.

As the Texians overrun the Mexican line at San Jacinto, General Castrillon crosses his arms with his sword in his right hand. As he strikes his pose, his sword flutters quite a bit, and the blade even appears to be warped. Hardly something anyone would take into a fight.

When Crockett plays the fiddle to play during the "Slit Throat" march, it is perfectly in tune, though presumably he hasn't played the instrument in days and began playing with no time to tune it.

The defenders of the Alamo, near the start of the movie, are singing "Listen to the Mockingbird." The Alamo siege took place in 1836 and "Listen to the Mockingbird" was written by Septimus Winner under the name of Alice Hawthrone and copyrighted in April 1855, 19 years after the siege of the Alamo.

One of Santa Anas aides mentions that Davy Crockett could shoot a fly at 180 meters. The metric system wasn't adopted in Mexico until 1857, 21 years later. Even then, it wasn't in common use until the 1890s.

In the scene before Travis asks the black guys to dig a new well; behind the two Alamo men discussing what's changed during the night, you can see a crew member in white T-shirt and white trainers walking backwards in the distance.

After Crockett plays his fiddle along with the Mexican death march and they don't bombard the Alamo as usual, he says: "Amazing what a little harmony can do." In fact, Crockett was playing counterpoint, not harmony.
