Late Night with the Devil star David Dastmalchian says the film's demonic talk show has something in common with Heath Ledger's Joker.

"The Cairnes brothers sent me a bunch of footage that they accumulated of Don Lane. He was the Johnny Carson of Australian television. He did this famous interview with Tom Waits, and a lot of people think Heath Ledger took inspiration from it for his portrayal of The Joker," Dastmalchian told The Hollywood Reporter. "[The likelihood of shared inspiration] is pretty cool, and it’s also the cyclical nature of being a storyteller and the strange path that it’s followed."

The interview in question was broadcast on late night Australian TV in 1979, and involves a very calm Don Lane and a rather chaotic 29-year-old Tom Waits. A seemingly inebriated Waits sits down next to Lane, and when you fast forward to the 1:45 timestamp – your jaw will drop. Waits' voice is near-identical to the one Ledger used for The Dark Knight's Joker, and the mannerisms are similar as well. Oddly enough, Dastmalchian had a small part in The Dark Knight as Thomas Schiff, a cop who is revealed to be a henchman for the Joker.

The found footage horror, written and directed by Cameron and Colin Cairnes, stars Dastmalchian as the host of a 1970s talk show who invites an allegedly possessed young girl onto the show for a special Halloween broadcast with the hopes of boosting his ratings. The film made (and we're not kidding) $666,666 at the box office in its opening weekend.
