For the episode "Nocturne", Entity FX ran into a snag when it came time to create the image of the episode's villain grabbing hold of a LuthorCorp helicopter. Mat Beck did not want to "cheat" the audience by using a cut technique to show Byron holding the helicopter; instead, Entity FX used CGI to create an entire helicopter. From there they decided they wanted the helicopter blades to cut-up the hedges. The special effects team tried to track Sean Faris' hands, as he was holding onto a crossbar that represented the helicopter's skid, to find a spot where they could make the helicopter roll toward the hedge. Unfortunately, Faris did not move in a manner that they could use, so the effects team created a pair of CGI hands on the skid, and performed the action they needed with the computer model. In "Dichotic", guest star Jonathan Taylor Thomas plays Ian Randall, a high school student who can duplicate himself. To create the effect of Ian splitting himself, Entity FX used three difference techniques. First, the primary shot of a CGI face pushing its way through a digital image of Thomas' back in three dimension; second, the team used "shadowplay", which is a two dimensional shot appearing on a wall as though the audience is seeing Ian's shadow as he splits himself; last, the team applied another two dimensional effect to the final moment of separation, when strands of CGI flesh snap back to each body. Entity FX worked on the scene in "Fever" where the audience follows kryptonite particles down into Martha's lungs. Mat Beck and his team wanted to be as realistic as possible when digitally crafting the anatomy of the lungs, but they also decided to take certain liberties with the structures in order to "make look cool". The camera follows the green kryptonite particles down Martha's throat, until they attack the alveoli, which subsequently begin turning green.
