Wa Hoo . Longer ago than I care to remember I had the great fortune to meet Einstein. I was an under grad in college when he made one of his unannounced visits to the campus. Walter Matthau captures the professor briliantly and his humor and wit come through in this film. Einstein's interest in motorcycles and his love of sailing are portrayed lovingly and the very human side of the great man is illustrated with fidelity and humor. It is always on my list of ten favorite films.
Output:
POS
