The 1980 biographical sports film Raging Bull transcends both genre descriptors often attached to it. Yes, it tells the true story of Jake Lamotta, an Italian-American boxer who hit his peak in the 1940’s and 50’s.

So technically it is biographical and about sports, yet neither of these words leap to mind when trying to summarise the experience it delivers upon the rolling of the credits. When approached to direct it, Martin Scorsese was initially disinterested as he “always thought that boxing was boring”.
