“Then we had to go into his eye. That means you have to find a transition to go from something that is projected into something that is full CG. And then you get the mini-Strange coming and going into the pupil as well as to transform into a tunnel with all the effects that goes around because the iris is becoming very reflective with this kind of a waterfall-like effect with a lot of energy going around. So it’s all transitions, and the difficulty was we need to make from one stage to the other very smoothly.” – Method Studios vfx supervisor Olivier Dumont.
