Character mistake: In a conference with Crockett and Bowie, Travis states that Fannin in Goliad is preparing to relieve the Alamo and will be ready to "march south by the end of the week." Goliad is 90 miles south of San Antonio. To relieve the Alamo, Fannin would need to march north.
The Alamo (1960)
1 character mistake - chronological order
Directed by: John Wayne
Starring: John Wayne, Richard Widmark, Laurence Harvey, Frankie Avalon
Factual error: Approximately 2 hours and 10 minutes into the "restored" full-length video version, there's a birthday party for little Lisa Dickinson, and the Alamo defenders sing "Happy Birthday" to her. The Alamo battle happened in 1836. According to David Ewen's "All the Years of American Popular Music," the song "Happy Birthday to You" was composed and copyrighted by sisters Patty and Mildred J. Hill, first as "Good Morning to All," in 1893.
Jim Bowie: I'd hate to say anything good about that long-winded jackanapes, but he does know the short way to start a war.
Trivia: Lisa Dickerson is played by John Wayne's real life youngest daughter Aissa, who was 3 in 1959. When she had to say hello or goodbye to Davy Crockett, she kept saying "Hello Daddy" or "Goodbye Daddy." Her lines had to be dubbed in later.
