Warner Bros. is currently lighting up the internet with trailers, having debuted the first footage from Steven Spielberg's Ready Player One just an hour ago and, now, four minutes of Justice League action.

While it doesn't tell us all that much - other than introduce Ciaran Hinds (yes, respected Irish thesp Ciaran Hinds) as Steppenwolf, make nods and winks to the Green Lantern and the Penguin, and definitely showcase how different and lighter the tone is from Batman v Superman: Dawn of Justice.

Not only that, it's clear Joss Whedon's reshoots of Justice League are having an impact, as there's that same overly verbose brand of comedy there that he's used successfully in Buffy The Vampire Slayer and, more pointedly, The Avengers.

So, that's enough filler. Here's what you came for.
