Humphrey Bogart was popularly known as the “Bogie” of show business in his time in Hollywood. Given the fact that he fought in the navy during the First World War, it was an apt moniker. When he was assigned to the military police, he was once struck in the mouth by a prisoner who had been beaten up. The accident did not prove fatal, but it did leave a scar on his mouth, which resulted in a little lisp as a result of it.
Because of his unique injuries, which was complemented by a raspy voice, he acquired the tough guy gangster persona for which he became well-known throughout his second acting career. On more than one occasion, even though he appeared to be the ultimate evil guy at moments, the actor suffered from stage fright, causing the audience to find it humorous.
