Trivia

In 2014, during a performance of "Cat on a Hot Tin Roof" - where he played Big Daddy - he broke character and went off the stage to confront a disturbed audience member who kept shouting ant-gay slurs towards Brick (played by Anton Troy), the oppressed gay character from Tennessee Williams classic play. The drunk guy in the audience challenged Lacy after being reprimanded by the actor. Lacy got off the stage and pushed the man, who fell instantly and was later removed from the theater by another audience member, the filmmaker Tim Sullivan. While many media outlets and the public praised Lacy's act, it wasn't good enough for the producers of the play and they decided to fire him; in protest, many of the principal actors (including Troy) decided to quit and the production was canceled. A few days later, the play was revived through NOH8 Fundraiser.

The late novelist Richard Yates was John Lacy's Godfather. Yates' 'Revolutionary Road' was adapted into a film directed by Sam Mendes and starring Leonardo DiCaprio and Kate Winslet.
