Michael Corner acted as Forrest Gump at his young age. He aced the performance and it would be expected that he would continue with his acting career. However, he joined the army and dropped the acting career.
According to the Film’s director, all the songs that were played in the movie were from American bands. He said that Gump would not have accepted anything that was non-American.
When Forrest met JFK, he says he was so thirsty rather than hungry. He said he drank 15 Dr. Peppers.
