Layton Well is an upcoming character on TNT' Snowpiercer. He will be portrayed by Daveed Diggs.
He is a quiet thinker who spends his days sniffing the industrial-waste-turned-drug Chronole and tending to his cage of rats. He is a prisoner barely surviving the harsh conditions in the tail end of the train and a reluctant participant in a struggle that could upend life on the train.
