I see Frost and Wu from Into The Badlands are in this.
Hannah John-Kamen is in this as well. The character she plays on Killjoys is a lot like the charming Lara Croft before the video game reboot happened that I miss. She's reportedly playing Lara's flatmate and best friend.
I suppose Vikander's Croft grows into that role by the very end.
As for the trailer, it sets up the premise well enough but I'm not totally sold on action Alicia with the VFX yet (and VFX usually get better the closer to the movie locking behind the scenes), rather sold on her emotional range where I wonder just how often this script allows her to stretch to that.
