The scene in the train station between Oliver and Bobbie takes place under the famous Carnforth Train Station clock, which appeared in Brief Encounter.
Stacie Swindells appeared as Leah, Bobbie's long-suffering girlfriend, but her scenes were cut from the finished film.
Janine Bebbington took over editing late in post-production.
The locker scene between Bobbie and Jason took over two hours to film.
All of the fight scenes were choreographed by Tom Jackson.
