Each of the robots were built both in real life and CGI. For certain shots with animatronics, they were controlled by more than twenty puppeteers.

Given that Hugh Jackman is left-handed, Atom is seen at times mirroring Charlie rather than mimicking him. In many scenes, especially in the fight between Atom and Zeus, Atom is clearly fighting right-handed while Charlie is shadow boxing left-handed. This is perhaps the reason why Atom is seen to be alternating between mimicking and mirroring even though according to how shadow boxing is explained in the film he should be only mimicking. This is also easily seen, though, when you notice the person running the shadow function either facing Atom or not. The shadow apparently mirrors when the operator is facing him and in mimic when not.
