Video shows Kate McKinnon’s dramatic transformation on ‘Saturday Night Live’

The actors and producers on “Saturday Night Live” make seamless transitions between sketches every Saturday night, fearlessly working against a ticking clock.

But have you ever wondered just exactly how the magic is done?

Well, the sketch comedy show has offered viewers a peek into the madness that happens behind the scenes.

This video from “Saturday Night Live” shows how costume designers transformed actress and comedian Kate McKinnon from Attorney General Jeff Sessions to Shud the Mermaid — in just one commercial break.

McKinnon went from donning a “simple” suit-and-tie outfit, to being fitted with prosthetics and face makeup in just four minutes, thanks to the magic of makeup.

The resulting sketch from the March 11 show starring Scarlett Johansson can be seen below. (Warning: Video contains mature humor.)
