 Effects expert Mat Beck was instructed to create a visual sequence that showed Doggett and Lukesh traveling between the different universes . Various effects were tested , including characters disappearing into black holes as well as phasing through the air in a more " exaggerated " and " watery " way . Beck ultimately decided to use a combination of both effects . Separate shots of a morphing scene were taken : one of the actors , and one of the background . Beck then used software to morph the two together to make it appear as if they had vanished . Later , artistic touches were added in post @-@ production editing to give a more futuristic effect .
