Trivia

 * Black Mask is, so far, not only one of the few characters in the DC Extended Universe to be LGBT, but the first incarnation of Black Mask to be so. In the mainstream comic book continuity, Black Mask has always been depicted as straight.
 * Unlike recent DCEU antagonists, Ewan McGregor's performance as Black Mask was praised by film critics, much like Margot Robbie’s reprisal as Harley Quinn.
 * A reference to Black Mask was previously seen in Justice League, as a building of Janus Cosmetics can be seen as part of Gotham City's skyline.
 * This is the first live-action appearance of Roman Sionis, and the second live-action appearance of someone using the Black Mask identity. Black Mask had appeared in the first season of Gotham, although the identity of the character was Roman's father, Richard Sionis.
 * Roman is the first main antagonist in a DC Extended Universe film series who doesn't have any superpower or cosmic abilities, and his motives are much lower scale compared to previous main villains as he only wants to rule Gotham City.
