Adult Swim Announces Halloween 2020 Marathon Featuring Original Series

This Halloween, stay up late with Adult Swim for some spooked-out treats beginning Friday, October 30 at 9:00 p.m. ET/PT. The evening starts with a marathon of themed episodes that lead to the Adult Swim Smalls premiere of Jack Stauber’s OPAL at midnight ET/PT, followed by Smalls-O-Ween at 12:15 a.m. ET/PT. The fright fest continues on Halloween as Toonami fans will be treated to a season one marathon of the suspenseful thriller, The Promised Neverland, starting at midnight ET/PT.

Jack Stauber’s OPAL is a new animated special by creator Jack Stauber (SHOP: A Pop Opera, Now and Then). Using a unique blend of stop-motion, 2D animation and musical elements, Jack Stauber’s OPAL tells the story of a curious girl who investigates the cries she hears coming from a forbidden house across the street. The quarter-hour special is executive produced by Dave Hughes (Off The Air, Adult Swim Smalls), Matt Harrigan, and Keith Crofford, and produced by Williams Street Productions.

Smalls-O-Ween are bite-sized shorts for your Halloween haul of previously released shorts that match the evening’s genre.
