Watch Galileo

"Galileo" (1975) is a film adaptation "The Life of Galileo" by Bertolt Brecht. Like the play, the film concentrates on Galileo's involvement in the controversy over heliocentrism, which is the principle that the Earth moves around the sun. Galileo had a telescope, which was new and cutting edge technology in the 17th century, and used it to bolster the arguments for heliocentrism. His doing so angered the Catholic Church which held that God had put the Earth at the center of the universe.
