Frank "Peter" Petrella helped world middleweight champion Jake LaMotta teach actor Robert De Niro how to box for the Academy Award-winning film Raging Bull. Now Petrella's daughter is taking those fight lessons into a different arena — the U.S. Supreme Court.

In Petrella v. Metro-Goldwyn-Mayer Inc., Paula Petrella asks the justices to give her the chance to prove that MGM infringed the copyright on her late father's screenplay which, she contends, formed the basis for Raging Bull, considered one of the best films ever made.
