Ostrum was in the sixth grade and performing at the Cleveland Play House children's theatre, when he was noticed by talent agents who were searching nationwide for the actor to portray Charlie Bucket in Willy Wonka & the Chocolate Factory. The agents took Polaroid photos of Ostrum and recorded him reading from the original novel, then returned to New York. Two months later Ostrum was called to New York for a screen test where he sang "My Country, 'Tis of Thee",[2] and a month after that he was contacted and given ten days to prepare to leave for filming.[7] Ostrum left for Munich on August 10, 1970.[5]
