Alien outcasts run amok on planet Earth in Roy Spence's sci-fi romp, a film that draws on the lo-fi charm of Ed Wood and Roger Corman. 

The story of three criminals exiled from their home planet for their heinous crimes, who end up causing havoc on earth. The plot of the Tryzzian Exiles would be echoed years later in Superman II. Shot on a somewhat more modest budget, this Roy Spence offering made great use of local landmarks, such as Carrickmannon Lake and Scrabo quarry.
