Watch: Actor Ezra Miller Kisses Fanboy at Comic-Con

Ezra Miller made things extra exciting at San Diego Comic-Con this year when he unexpectedly locked lips with a fan.

Miller will play The Flash in the upcoming "Justice League" film, and will later get his standalone picture. It seems as though the "Fantastic Beats" star is his knowledge on The Flash to new levels. In a video posted by TMZ, Miller, 24, is seen explaining to a crowd why it would take a lot of booze for the superhero to get drunk (it's because The Flash has a fast metabolism).

A male fan asked a hyped-up Miller to smell his breath but the actor gives him a little more than he likely anticipated by laying a big wet one on him. Of course, the crowd goes wild.

In 2012, Miller came out by identifying as queer in an interview with Out magazine.
