The Giant Gila Monster, 1959

The Giant Gila Monster is a 1959 American monster film directed by Ray Kellogg and produced by Ken Curtis. A famous B-movie of the era, the film stars Don Sullivan, a veteran of several low budget monster and zombie films, and Lisa Simone, the French contestant for the 1957 Miss Universe, as well as comedic actor Shug Fisher and KLIF disc jockey Ken Knox. The effects included a live Mexican beaded lizard, instead of a Gila monster, that was filmed on a scaled-down model landscape.

Filmed near Dallas, Texas, the film was budgeted at $175,000 and was produced by Dallas drive-in theater chain owner Gordon McLendon who wanted co-features for his main attractions. McLendon shot the film back to back with The Killer Shrews. Both films were feted as the first feature films shot in and produced in Dallas, and the first movies to premiere as double features. Unlike most double features released in the South, these films received national and even foreign distribution.
