If you want a movie that can show you how a shadowrun can be botched, watch the Ladykillers with Tom Hanks. It's funny, and anything bad that can ruin a plan happens. Recommeded for comically evil GM's.
Doom the movie hits my list as well. High tech (Ignore the teleportation for now. . .) Lots of guns and assume the demons are just angry spirits. Pretty good for a gritty-about to die- situation.
The Alien Series, has some valid points about advanced tech, AI, and paracritters.
