Glass Trap is a 2005 American science fiction horror film starring C. Thomas Howell, Stella Stevens & Chick Vennera (in his final film) and directed by Fred Olen Ray, credited as Ed Raymond.

An army of giant, radioactive ants are accidentally trapped in a skyscraper, and a group of employees must band together to escape the building.

[1] David Cornelius from eFilmCritic gave the film 2/5 stars, writing, "Like many direct-to-video features, Glass Trap will do the trick for those who rent these kind of things.

It's harmless in its dumbness, painless in its 'gee, get a load of these fake ants we whipped up' presentation.

"[2] Chris Hartley from Video Graveyard gave the film 1.5 out of 4 stars, criticizing the film's dialogue, weak special effects, and poor attempts at humor.
