TeenAlien (1978) Kids decorating an old mill for a Halloween party find something living there. Running time: 88 minutes. Minus aimless walking about: maybe 50-60. TIL: Jesus walked over 3,000 miles during his 3-year ministry. The Bible didn't feel the need to detail every step.
Tail Sting (2001) No snakes, just dog-sized mutant scorpions on a plane. Alas, no Sam Jackson, but kudos for using big goofy puppets instead of CGI. TIL: The power to tread on scorpions in Luke 19 is not literal (mostly), but in context means the ability to stomp spiritual evil.
