It's time to choose teams and don your bat ears or red capes, because the Batman v Superman: Dawn of Justice trailer will premiere on Monday, April 20. Director Zack Snyder tweeted the news on Thursday, also teasing that there will be special advance screenings. The best part is that he released a short teaser ahead of the full trailer. Stars Ben Affleck and Henry Cavill are absent, but their suits are on full display. Still no Jesse Eisenberg, who rocked a bald head in the first look at him as Lex Luthor. Take a look at the teaser, check out all the pictures so far, and start getting emotionally prepared for the big trailer!
