Critters 4 is a 1992 American science fiction comedy horror film starring Don Keith Opper, Terrence Mann, Angela Bassett and Brad Dourif. It is the fourth installment in the Critters franchise, filmed simultaneously with part three, from February to July 1991. Unlike the first three films, this installment adopts a darker, less-comedic tone, and takes place not on Earth, but on a space station in the year 2045.
