Blasts from the Past

 

Calvin (Christopher Walken) is convinced the US is about to be bombed by the Russians and has built an extensive bomb shelter for himself and pregnant wife (Sissy Spacek).  There is no bomb, but a plane crashes into their house while they are in the shelter and he thinks that the bomb has surely exploded and sets the lock on the shelter for 35 years, after which it will be safe to emerge.

Son Adam (Brendan Fraser) is born in the shelter and raised there for 35 years, at which time the locks open and Adam emerges from the shelter to replenish the food for his family.  He knows nothing of the world of 1999 and manages to meet Eve (Alicia Silverstone).  All sorts of things happen, but she finally realizes that he 's telling the truth and he finally brings his family to the surface and all ends happily, though Dad still thinks the story about the plane was a hoax.

A fun comedy and I enjoyed it a lot.
