After graduating from Weslyan University, John Buffalo Mailer founded Back House Productions in New York City with three of his fellow grads. Within one year Back House became the resident theater company of The Drama Bookshop's Arthur Seelan Theater, and developed several plays, including the 2008 TONY Award Winner for Best Musical, "In The Heights". In 2001, John's first play, "Hello Herman", had its New York Premiere at the Grove Street Playhouse. The play is about a High School shooter being interviewed on death row three days before his execution. In 2009, the Edgemar Center For The Arts in Los Angeles opened the West Coast Premiere with John in the lead role opposite Sawyer Spielberg. Dramatists Play Services published Hello Herman in the Spring of 2010, prompting Smith And Krauss to include an excerpt of the play in their Best Monologues of 2010 publication. The feature film, which John adapted himself, is currently in post-production and stars Norman Reedus and Garrett Backstrom. The film was directed by world renowned acting coach, Michelle Danner. A trailer for the film can be viewed on YouTube. John's second play, "Crazy Eyes", had its world premiere in Athens, Greece in 2005, and the US Premiere in Provincetown, Massachusetts later that same year. Crazy Eyes, which takes place in October of 2001, in Park Slope, Brooklyn, centers on an actor, a day trader, an AIDS researcher, a bag of white powder, and a Palestinian American who owns the 99 cent store.

In 2004 he interviewed his father, Norman Mailer, for New York Magazine, on the possible dangers and benefits of the protests of the 2004 Presidential election. That interview was later included in a book of discussions between father and son on topics ranging from Protest to Poker and everything in between, titled "The Big Empty" (Nation Books, February '06). In 2008, in partnership with his brother, Michael Mailer, he produced the documentary adaptation of Naomi Wolf's New York Times best selling book, "The End Of America", as well as a National Television commercial directed by Oliver Stone.
