They're probably hoping Suicide Squad will do the same for them that Guardians of the Galaxy did for Marvel which was to launch a bunch of unknown characters into the mainstream.

How exactly they're planning to do that is still a mystery. I'll cross my fingers though, because DC really needs to get some good movies out there if they want to stay in the game.

These designs for the costumes are pretty adequate, I guess only time will tell if their performances and directing will be any good.
