The Tower (1993)
I vaguely remember watching this almost-completely-forgotten Paul Reiser made-for-TV vehicle when it was on TV back in the ‘90s, and have been wanting to rewatch it for ages. I remember it being pretty cheesily terrible, but little did I know, the entirety of it was on YouTube.
In this classic case of “computers gone wild", the so-called "smartest building in the world", nicknamed CAS, decides Paul Reiser is a major security threat based almost entirely on the fact that he is acting like Paul Reiser. (Depending on how you look at this, this is either a service to mankind or rather unfair to Mr. Reiser, who can't help but push the elevator button too many times. Which, according to CAS, is a major security violation worthy of self-destruction and multiple homicides.)
This movie has everything - love, laughs, little-to-no logical consistency, an exploding sauna. (Also an extended scene of Paul Reiser attempting to compose the soundtrack for the movie in his underwear before work.) It’s an amusing 80-or-so minute watch even without the gang riffing over it, but I think it would be a perfect candidate for the full-out RiffTrax experience.
