Cujo
Like Firestarter, this 1983 release is another Stephen King adaptation that makes heat one of its horrors. (He also has quite a few stories that make you fear the cold, too.) Yes, the rabid dog is the primary antagonist, but the situation is made so much worse by the fact that the main characters have to take refuge in their car with all the windows rolled up. Being ripped apart by a massive canine is almost preferable to a slow, agonizing death by heat stroke. Stream on Max.
