The Flame Barrier is a 1958 American jungle adventure/science fiction film produced by Arthur Gardner and Jules V. Levy, directed by Paul Landres, and written by Pat Fielder and George Worthing Yates.

Howard Dahlman (Dan Gachman), a rich businessman and ardent amateur space program enthusiast, went into the Mexican jungle to recover the satellite, but never returned.

Arriving in Campeche, Mexico, Carol meets two jungle guides, the ill-tempered Dave Hollister (Arthur Franz) and his drunken but good-hearted brother, Matt (Robert Brown).

To everyone's shock, the man's body suddenly bursts into flames, leaving a skeleton similar to the one they had found earlier.

Daily Variety reportedly carried an item sometime in July 1957 which stated that Gramercy Pictures purchased an original story titled "The Flame Barrier" from author Sam X. Abarbanel and hired Yates and Fielder to adapt it into a screenplay.

[9][10] Upon its release in the UK, it was granted a U certificate by the British Board of Film Censors, where the "U" stood for "Universal" and allowed "anyone to watch it, with no restrictions whatsoever".

[11] The Flame Barrier was distributed to American theaters by United Artists as the bottom half of a double feature with The Return of Dracula.

"[12][13] The somewhat unusual mixing of jungle adventure and science fiction film elements has been noted by both the people involved in producing the movie and those who have commented on it.

Fielder told American film scholar Tom Weaver in an interview, "I think we were kind of following a pattern of other jungle movies of the time - but there had been the event of a Sputnik going up with a monkey on board".

He also noted that The Flame Barrier - like the other Gramercy Pictures horror/sci-fi films The Monster That Challenged the World, The Vampire and The Return of Dracula - was "not very profitable.

[14] BoxOffice called The Flame Barrier "wild and wooly" with "sufficient excitement" to "satisfy the most action-minded fan", but also referred to its "opening scenes" as "rather routine".

Saying that the film "builds up suspense steadily", the magazine predicted that "teenagers will overlook the fact that this is routine entertainment and go for it in a big way" while "adult males will accept it" as the second half of a double feature.

Like Hardy, he pointed out that "it was designed to capitalize on interest in satellites" and said that the alien protoplasm "looks more like crumpled cellophane than jelly".

He went on to call the film "singularly dull" and pointed out that "there is no flame barrier in reality, and it has no real application to the movie".
