According to TV Guide, the movie was "one of the first Hollywood films to deal with the plight of Vietnam veterans".
The scenes where Jack and Carol are hitchhiking on a road alongside giant redwood trees was shot within feet of the future location of George Lucas' Skywalker Ranch.
This was the first movie that Harrison Ford was seen in after the sci-fi blockbuster स्टार वॉर्स (1977) (released just two days before the release of Smokey and the Bandit (1977) which also starred Sally Field) though the picture was actually filmed before that.
