This shot is a combo of two pieces of animation. One is the prisoner removing the pin from the carriages and the other is the Bandit's gasping reaction. Above is the playblast of the animation which I am quite happy with. Also below I have done a comp test to show how the shots will fit together using an alpha of a ripped/torn piece of paper which fits in with the roughness of some of the elements. The black region is where the Bandit will be positioned and Matt can use this as a guide for the animation. Also he will use my timings to judge the timing of the expression animation.
We may also use this device again in the film to make it not seem like a one off style as we want to incorporate a marshal close-up reaction during the fight scene.
