The end result delivers plenty of chaos in a tight, deliriously over-the-top 77-minute package - and it's all the sweeter for having using recycled props, costumes, sets, footage, etc. in the process. Forbidden World is thus a model of Corman's recycling aesthetic and a perfect companion piece to Galaxy Of Terror.

…one of the most unique knockoffs in the Roger Corman production-canon is Galaxy Of Terror. It was designed to be the drive-in version of Alien and it delivers handsomely in that regard while also dishing out some surprises that will shake the audience up.
