Brian Duffield (born November 5, 1985)[1] is an American screenwriter known for his frequent feature script sales in the 2010s, which include the screenplays for The Babysitter (2017), Underwater (2020), and his 2011 Black List scripts Jane Got a Gun (2015) and Your Bridesmaid is a Bitch.[2][3]

Early life[edit]

Duffield grew up in the suburbs of Pennsylvania with his parents, Brian and Brenda Duffield, and two sisters.[4] In 1995, at nine years old, he moved to Ireland when his parents decided to become missionaries.[5][4][6] He described the surroundings as completely remote and lagging in popular culture.[4] Duffield attended school where in one classroom, three grades were being taught by one teacher, which he described as very "Little House on the Prairie-esque".[4] He moved back to the US when he graduated high school in 2004.[4]

Duffield graduated from both Temple University and Messiah College in 2008.[7][6] After graduation, he moved to Universal City, California for a summer internship through Temple University at the Oakwoods apartments prior to the 2007–08 Writers Guild of America strike and at the beginning of the Great Recession.[7][8]

From there, Duffield worked various jobs before becoming a professional screenwriter. His first job in Los Angeles was at the now defunct Storyopolis, a children's book store/art gallery, in Studio City, where he worked with writer Blake Harris.[7] He has also worked as an assistant and script reader within the film industry for several years.[5] Prior to selling his first spec screenplay, Duffield was temping at the Lucky Brand Jeans factory in nearby Vernon, California.[9]


Duffield first spec sale was for Your Bridesmaid is a Bitch to Skydance Media.[2] The story is partially based on his personal experience with his friends' weddings and a slew of failed relationships.[5] His friend from college had sent a copy to a contact at Circle of Confusion management company, who later offered to be Duffield's manager.[5][2][10] Several days later, they got a meeting with Skydance, who bought the script.[2][5] Eli Craig was last attached to direct and rewrite the film in May 2015.[11] Black List Live!, a live monthly stage reading of scripts featured on the Black List, did a performance of Your Bridesmaid is a Bitch in 2014.[12]

Duffield sold his script for Monster Problems to Paramount Pictures in 2012.[13] Matthew Robinson was later brought on for rewrites and Michael Matthews is set to direct the film.[14]

Duffield's first writing assignment was for the film adaptation of the second book in the Divergent trilogy, Insurgent (2015), in 2013.[15][7]

The script for The Babysitter (2017) was sold to McG's company, Wonderland Sound and Vision, at auction.[2] McG also directed the film, which later premiered on Netflix in October 2017.[16]

His film Underwater, starring Kristen Stewart, premiered in 2020.

Personal life[edit]

Duffield is married.[2] His parents still reside in Ireland.[5]
