Emmy winner and Ray Bradbury superfan Bill Oberst Jr. has portrayed many characters who reflect the darkness within mankind; in his new one-person show, “Adversary,” he takes on the Devil himself.

Presented as part of the IU Indianapolis Ray Bradbury Center “Festival 451 Indy,” Oberst’s performance in the District Theater, Sept. 30-Oct. 1 is the world premiere. (If you are seeing this as it is posted, you may be able to make the 2 p.m. Sunday show.)

Satan, who enjoys toying with the words of others, regards himself through sources ranging from ancient scripture to Mark Twain. Oberst contributes one piece, “Your 3 A.M. Therapist.” Mr. Bradbury is not quoted, though this suits the literary mission of the festival, and Oberst said in a follow-up Q&A that Bradbury’s character of Mr. Dark in “Something Wicked This Way Comes” was an inspiration – one of the better depictions of the Devil in fiction.

“Here we hear lies; here we hear truth,” the entity before us declares. “The devil is in the distinction.”

He focuses on three principal “true lies” that sound good and right but are bendable to darker purposes. Passages such as Fyodor Dostoevsky’s “The Grand Inquisitor,” from “The Brothers Karamazov,” show their application.

It is sometimes said that a work of theatre challenges you in the audience. This one literally does. Old Scratch knows you are watching and speaks to you through the ephemeral fourth wall. Do you answer? Regardless, there is plenty of food for thought here – dine with care.

“Adversary” is a unique, engaging, and in its own dark way enlightening theatre experience. For more information on Oberst and his projects, visit billoberst.com; click here for the Ray Bradbury Center in Indianapolis.
