Fences
He was outstanding in Fences - Viola Davis rightly winning for her performance and being in it much more than Jovan she's very obviously brilliant. But I hadn't heard about Jovan before watching this, and I just thought he dealt with his scenes incredibly powerfully. Even just in the way he stood there and took it from Denzel was great, but he really got me on the steps with his little sister at the end.
Look forward to seeing what else he does.
