Answer: Professor
Calvin, the father in Blast from the Past, was a professor. In the movie, he is a brilliant scientist who builds a fallout shelter in the 1960s to protect his family from a nuclear war that never happens. He raises his son, Adam, in the shelter for 35 years, teaching him everything he knows. When Adam finally emerges from the shelter in the late 1990s, he is amazed by the changes in the world. Calvin's profession as a professor is a key aspect of his character, as it explains his intelligence and resourcefulness in building the shelter and preparing for the worst.
