Also, for the Final 22, I'd also like to support:
The Night Stalker (1972 TV Movie) - A classic, always highly rated, thoroughly enjoyable. Best made for TV I've ever seen, any genre. "An abrasive Las Vegas newspaper reporter investigates a series of murders committed by a vampire." Can see full film on Youtube.com for free

If I were to support more than 2 films for the 22:
Magic (1978) - fascinating, and unusually scary film about a ventriloquist (Anthony Hopkins) who can't put his dummy down, even for 20 secs... he's insane. Directed by Richard Attenborough. also starring Ann-Margret, and Burgess Meredith.
The Andromeda Strain is a great film, I just don't consider it Horror.
