You’ll no doubt be hearing a lot about Panos Cosmatos’ cult fave Mandy in the coming months, as it’s sure to be headlining countless end of the year “Best Of” lists across the internet. You can currently rent the film on VOD or pick up a physical copy, and we’ve learned today that Shudder will become its exclusive streaming home on November 29th.

In the meantime, concept/storyboard artist Rob McCallum just shared some cool pieces of concept art from Mandy with Digital Arts Online, in addition to providing some insights.

“After reading the great script by Panos and [writer] Aaron Stewart-Ahn, I did some roughs and Panos could pick and choose what he liked to develop further,” McCallum explained to the site. “He’d send photos of textures and shapes – one email of pics had a lovely pic of David Lee Roth in full metal pose at the end captioned DAVE. I’d work from those onto what would eventually become the final design.”
