Alligator Watch Order

Alligator films in order, from Lewis Teague 1980 original with Ramon flushed to sewers to Mutation in 1991 at the lake. John Sayles scripts the first with Robert Forster, so release order is the only path with the original as the stronger start.

Two films in release order.

About Alligator

Alligator (1980) follows Ramon growing to thirty six feet on lab dogs in Chicago sewers, pursued by cop David Madison and expert Marisa Kendall. Produced for under two million, it built cult praise for practical effects.

Alligator II The Mutation (1991) moves a new giant to a town lake with no returning cast, directed by Jon Hess. The plot repeats sewer to lake beats with carnival developer cover up. Watch the 1980 film first for growth hormone rules, then the 1991 sequel as a standalone variation with the same monster logic.

Good to know

Release order is story order since the sequel reuses growth rules without continuing characters. Start with 1980 for sewer hunt setup that defines the monster and its hormone diet. Mutation works only after learning the formula, so save it for second viewing. No third Alligator film exists, so this pair is complete.
