The Parts You Lose is a 2019 American thriller film starring Aaron Paul and Danny Murphy as a fugitive criminal and a deaf boy who befriend one another.

[2] The film originated in 2015 as a German-Canadian co-production based on a screenplay by Lemke and with Dutch director Paula van der Oest attached.

Actor Aaron Paul was cast in May of that year, with filming scheduled to begin in the Manitoba province of Canada in the last few months of 2015.

[5] By June 2017, the production-financing entity The H Collective was launched with The Parts You Lose among a dozen films it began financing.

[8] In the following December, actors Mary Elizabeth Winstead and Scoot McNairy were cast as the deaf boy's parents.

[9][2] McNairy had previously starred in the TV series Halt and Catch Fire (2014–2017), of which Cantwell was one of the creators and showrunners.

[9] Since Murphy and his character use sign language, producers involved students and staff from Winnipeg's Manitoba School for the Deaf.

And for such a bleak and harsh tale, The Parts You Lose finds some rays of light at the end of the night.
