Although details of the plot are scarce, many are describing it as a film similar to Taxi Driver and The King of Comedy, two Martin Scorsese films starring Robert De Niro, who also co-stars in this film. This film will not follow the same Joker as played by Jared Leto in Suicide Squad or even Heath Ledger in The Dark Knight.
This will be separate from the current string of DC Comics films based in the same movie universe and will serve as its own standalone film. In that sense, many are comparing its serious tone and isolation from tie-in to Logan.
Check out the footage above and catch Joker when it debuts October 4 with co-stars Zazie Beetz and Marc Maron.
