Mission Impossible face removal

[Ryan Hill]

I remember the old MI did a lot of stuff like: the guy reaches under his neck, starts peeling, cuts to another angle, finishes peeling with the new actor.

If you’re really set on doing it digitally for cheap, you could do a close-up of the first actor. Green screen his hands reaching up to grab his face, apply a distortion to the face to let it stretch out and pull off, revealing the second actor. It will look like the fakest thing ever, but if you make the right rubber noises, it’ll get the point across.
