Though Scorsese is one of Hollywood's most celebrated directors, it's an eye-opening reminder that the world almost missed out on his illustrious career–and he almost missed out on making it. Scorsese later claimed that because of the rough state De Niro had found him in, he was just lucky there was a project to be able to jump into at that point. Believing that Raging Bull was his last film, Scorsese gave directing it his all, saying that it was a ' culmination of everything he wanted to do' and was making it as if it were the end of his life. Martin Scorsese finally accepted De Niro's request to direct the film, trusting that he could distinguish it from other boxing movies at the time. This conversation is the reason Scorsese credits Robert De Niro and Raging Bull with saving his life.

It was after this near-death experience that Scorsese began to realize how closely he related to La Motta's self-destructive character. Robert De Niro visited Scorsese in the hospital after the incident and had a tough talk with him, asking him if he never wanted to see his daughter grow up, or make a movie ever again. In 1978, Scorsese was rushed to the hospital in critical condition, suffering from severe internal bleeding from a life-threatening drug overdose. After the underwhelming release of his 1977 film New York, New York (often considered one of Martin Scorsese's worst movies), Scorsese was on a downward spiral of self-doubt and depression, fueled by a substance abuse issue with cocaine. Yet a conversation he had with Robert De Niro at a critical point in his life turned Scorsese's mind around, not just on Raging Bull, but also on his life.

Scorsese had severe asthma growing up, so always felt very sheltered and kept away from sports, instead preferring to spend his time with films.

Martin Scorsese was initially resistant to Raging Bull, repeatedly turning down the opportunity to direct the film when approached by Robert De Niro.
