John Carpenter's Vampires/Ghosts of Mars

Double bill of horrors directed by John Carpenter. In 'Vampires' (1998), when Jack Crow (James Woods)'s team of mercenary vampire hunters is slaughtered by the master vampire Valek (Thomas Ian Griffith), he teams up with Montoya (Daniel Baldwin) to fight back.

Their only link to Valek is the beautiful, psychic prostitute Katrina (Sheryl Lee), and with her help they set out to confront the ultimate evil.

In 'Ghosts of Mars' (2001) the year is 2176 and Mars has been colonised by Earth, but the spirits of the old planet still continue to cause trouble.

When a police team travels to a distant Martian mining outpost in search of the mass murder suspect Desolation Williams (Ice Cube), they find the place populated mostly by headless corpses.

Williams is discovered locked in the town jail, and when the team is attacked by a mob of miners possessed by Martian spirits, it seems the jail might be the safest place for them all to be.
