A fun fact about the 1978 “Invasion of the Body Snatchers” remake is that they actually incorporate the ending of the original movie into the plot.
At the very end of the 1956 movie, the protagonist discovers the alien conspiracy, and with a number of the disguised humans not far behind him, runs into traffic trying to stop cars to warn them of the alien invasion. He finds a truck shipping the alien cloning pods to LA, San Francisco, and Seattle. Even more desperate, he stands in the middle of the highway yelling “They’re here already! You’re Next!”
Early on in the 1978 film, the same man (the same actor, Kevin McCarthy) stops the car of the new protagonists in the middle of a San Francisco road, and yells at them "You’re next! They’re coming!” before being chased away by a large crowd in pursuit of him. He’s then hit by a car and killed, while the crowd stands over his body and stares at his corpse.
