He's a talented young actor. I haven't seen the last two you mention, which are supposed to be very good and I'll try to catch them. I've seen him in Whiplash and the Divergent movies. He reminds me a little bit of a young John Cusack, only he's choosing more ambitious films perhaps.

Similarly, Ansel Elgort. I didn't think much of him until I saw him in Baby Driver and it changed my opinion. He was very convincing in the role, compelling. Two skilled actors with strong potential.
