Harry is part of the cast of a four-part series on Channel 4 that is currently filming. The Fear features Peter Mullan as the main character, and Harry as one of his sons.
(I realize that all the action is at Tumblr these days, but honestly? It's impossible to actually interact with anyone there, so I figured I'd keep posting here. Until the mods shut the joint down, lol).
Thanks to @Lloydalists for the news tip!
