That was the reason why for me. Shayera Hol is a very popular character amongst fans, and she's never quite made it to DC Comics, perhaps a depiction of her in a film could persuade DC to introduce this version of the character in the main continuity.

Also, should Hawkette be given her own film, I think it'd be great for Hawkman to be in the sidekick-type role, in contrast to the usual less prominent role of females in superhero movies.
