Dr. Seuss's The Grinch Musical premiered on NBC in the US tonight, and we finally got a closer look at Matthew Morrison as a truly frightening Grinch. Ahead of the live-action special on 8 Dec. (which is actually being filmed in London, the former Glee actor shared his epic transformation into the character, which included prosthetics, makeup, and a whole lot of green paint. Morrison documented the three-and-a-half-hour process and shared it all in a one-minute time-lapse video on his Instagram, and we have to say it's pretty damn fascinating.
As a makeup artist layered on the prosthetics, thick eyebrows, and green fur, the actor sat back in his chair as he munched on snacks and even played a few chords on a ukelele. From the green nose to the furry wig, the precision and accuracy of Morrison's transformation is truly unmatched, and quite possibly may appear in your nightmares. Check out the process in full above, and ahead, get a glimpse of the Grinch in action.
