The visual effects team was led by VFX supervisors Steve Cronin and Paul Story from Weta Digital who worked on the film at nights and weekends. The team completed over 200 visual effects shots, lifting the film and giving it a high action gun-slinging dynamic.
For Steve his involvement doubled into acting as one of the gun-slinging posse members. His character is shot in the film and he ended up not only creating that scene in front of the camera but then adding the visual effects to his own death in post-production.
