The majority of the film has been shot in
Wheeling, West Virginia. In December 2025,
Dianna Agron joined the cast, with
Eric Swalwell and
Sean Penn serving as executive producers. Later that month Penn and Swalwell removed their names from the credits of the film due to the film technicians strike.
Film technicians union strike In December 2025, a majority of film technicians working on
The Gun on Second Street announced their intention to unionize with the
International Alliance of Theatrical Stage Employees. After producers declined to recognize the union or enter into what IATSE described as good-faith negotiations, the crew initiated a strike on December 18, 2025, with IATSE directing its members not to cross the picket line. The production was covered by a
SAG-AFTRA agreement but not by contracts with IATSE or several other major industry unions. ==References==
