Unlike Suicide Squad, which looked like it was ripped from the pages of a comic book, Phillips' movie — to be produced by Martin Scorsese —is set to evoke the mood of movies like Taxi Driver . It will be a standalone origin story that does not connect to the films currently in the DCU. (Leto will reportedly appear in more movies in the Suicide Squad timeline, including the film's sequel and a Harley Quinn-centric spin-off.)
