'Birds of Prey (and the Fantabulous Emancipation of One Harley Quinn)' is easily one of the most highly anticipated movies of 2020 and we've been eagerly waiting to get more details about the film.

Now a brand-new teaser for the film has been released and it finally reveals why Roman Sionis / Black Mask (Ewan McGregor) is so desperately hunting Harley Quinn (Margot Robbie).

The film's official Twitter account shared the new TV spot on January 13 (which you can check out here) and it features some new, never-before-seen footage. Specifically, the teaser reveals that the Black Mask is trying to recover a precious diamond from the Birds of Prey, possibly after it was stolen by Cassandra Cain (Ella Jay Basco). 

Why's the diamond so important? We don't know that yet. Apparently it would make the Black Mask unstoppable, either because it has magic powers or simply because a tennis ball-sized diamond is worth a fortune.

The only magical diamond from DC Comics that immediately comes to mind is the Black Diamond of Eclipso, the gem within which the demonic entity Eclipso is imprisoned.

Seeing as the diamond in question doesn't appear to be hosting any malevolent demons (and it's not black), this seems unlikely to be the case though we don't have enough details about the movie's plot to dismiss the theory entirely.

Of course, Margot Robbie has mentioned in interviews that the movie will be taking a very grounded approach and we don't really see ancient magical entities fitting into the sort of film she said this would be.

"With my initial kind of pitch on the story, I said I wanted to keep it quite contained and kind of get no bigger, no world-ending stakes," Robbie told reporters, according to ComicBook. "Like the stakes were as big as perhaps mafia level, or gang level."

The teaser also includes new footage of Renee Montoya (Rosie Perez) and Dinah Lance / Black Canary (Jurnee Smollett-Bell). 'Birds of Prey (and the Fantabulous Emancipation of One Harley Quinn)' will arrive in theaters on February 7.
