William Shatner wrote the story (with Harve Bennett and screenwriter David Loughery) and makes his awkward if sincere directorial debut in this 1989 sequel—an exceptionally feeble entry whose ideas, visual and otherwise, consist of hand-me-downs from 2001, Star Wars, Blade Runner, and Superman III, and whose special effects, despite the hefty budget, look strictly bargain basement. The Enterprise crew (Shatner, Leonard Nimoy, DeForest Kelley, James Doohan, Walter Koenig, Nichelle Nichols, and George Takei) encounter a renegade Vulcan named Sybok (Laurence Luckinbill) who wants to usurp the starship for a dangerous quest to find God at the center of the universe. David Warner also stars, although it looks like most of his part wound up on the cutting-room floor.
