“When the movie was over, I couldn’t remember who I was anymore,” Jim Carrey says in the trailer for Jim & Andy: The Great Beyond. The film contains the long-awaited behind the scenes footage of one of the greatest and most controversial acting transformations in recent memory.

“In 1999, Jim Carrey portrayed his idol Andy Kaufman in ‘Man on the Moon’,” the description explains.  “For twenty years, the behind-the-scenes footage has been withheld…until now. Jim & Andy: The Great Beyond – With a Very Special, Contractually Obligated Mention of Tony Clifton premieres November 17th, only on Netflix.” And why was the footage withheld? Well, as the trailer explains— they didn’t want Carrey to look like an assh*le.

Carrey was fascinated and enthralled by Kaufman, an entertainer determined to push boundaries and commit to the most extreme extension of his characters and performances. Carrey was thrilled at the opportunity to play him and committed so wholeheartedly— both on and off screen— that there was an almost complete transformation. As the filming progressed he was no longer playing Kaufman, he became Kaufman.

And though for years the footage was kept hidden, the release of it shows just how far Carrey went. You can see the trailer here:

It looks mesmerizing, bonkers, and maybe even a little disturbing— but totally entertaining. Carrey is a genius performer who never feels the need to limit himself. Seeing himself go so far beyond normal constraints when becoming his characters is fascinating. “The material of him on set is unbelievable,” the Guardian says. “Watch him annoy the hair and makeup people with loud music, watch him crash cars on the lot and trespass into Steven Spielberg’s office. Gaze on with wonder as this pompous and very talented clown refuses to answer to the name Jim.” Luckily, we can all gaze on in wonder when the film appears on Netflix— this November 17th. It should be a sight to behold.
