Character Analysis
Carlo, played by Gianni Russo, is a thoroughly detestable character. Not only does he brutally beat his wife, Connie, and cheat on her, but he also helps plot Sonny's murder.
He attacks Connie with a belt in order to force Sonny to leave the family's compound, leading him into a death trap at the toll-booth. But he gets his—the movie begins with his wedding to Connie, but it ends with the aftermath of his demise. Michael identifies him as the traitor and, while pretending that he's going to let him move to Las Vegas and live, he has him killed in the car outside.
