We also catch glimpses of Robert De Niro's Murray Franklin, a talk show host who plays a role in Arthur's dark turn, and Zazie Beetz's Sophie Dumond.

Todd Phillips directs the film, which debuts in October and has an R rating. Phillips also revealed that the film's story will be completely original, and won't follow any previously published DC comic books or movies that feature the Joker, who's traditionally Batman's nemesis.

Joker hits theaters worldwide on Oct. 4.
