5. Pre-Robin

In the final scene of “The Dark Knight Rises,” John Blake, portrayed by Jewish actor Joseph Gordon-Levitt, revealed his full name: Robin. So, if you decide to do this, put on a cop outfit and tell people who don’t believe you are Robin that you will arrest them.

J-Connection: Joseph Leonard Gordon-Levitt was born in Los Angeles, California to Jewish parents who were among the founders of the Progressive Jewish Alliance.
