The initial script that Howard Hawks intended to direct truly reflected the character of Camonte. In both endings it starts with Camonte being distraught after his sister, Cesca is shot. He becomes frantic and begs for Guarino to stop shooting at his window. Then he staggers down the stairs shooting at the back door where Guarino waiting for him to escape. Due to the fact there were censorship barriers Hawks he had to obey there are two endings filmed for Scarface. The uncensored version is the “coward’s run” ending in which Camonte and Guarino exchange shots but Camonte shot is blank. Then afterwards Camont tries to get pass Guarino . The scene ends with Camonte being gunned down at the front steps. On the other hand, during the “trial” ending Guarino arrests Camonte then he is taken to trial. The judge decides to sentence to death and the film ends with Camonte being hung.
Throughout the film Camonte is portrayed as fearless. I think the original ending follows that trend with Camonte boldly charging at Guarino to end his life with dignity. He knew his life was ending at that point and he bravely died as a gangster. He didn’t shy away from the challenge of trying to kill Guarino first before he got to him. Alternatively, I think the censored ending is the political correct ending for the film and it didn’t glorify Camonte’s character.
