Even though Billy wasn't the best guy, we can't say that we won't miss Dacre Montgomery on Stranger Things. While we don't know if Billy will pop again in flashbacks or otherwise, Montgomery will still be around. He appears in this year's The Broken Heart Gallery, a film about a lovelorn New York curator who collects items related to breakups. The movie adaptation of Peter Carey's book True History of the Kelly Gang will also feature him alongside Russell Crowe and George MacKay.
