Mutant Species (1995)

A rocket containing bio-hazardous material to be disposed of by launching into space crashes in a remote wooded area. An army team is sent to recover it. One of the men is infected and mutates into a monster, killing most of the rest of the team. One man escapes with the help of a brother & sister who live in the woods. He then tries to stop his former buddy, while also fighting against another army team sent in to destroy everything. The bio-material was supposed to create a super-soldier, was banned, and the crash of the rocket appears to have been deliberate so the experiment could proceed. But who is behind it all? And will others be infected?

Unfortunately the movie Mutant Species is not yet available on HBO Max.
