The actor exclusively told DS that he would be interested in reprising his role as Harvey in a '90s-set follow-up.
"I hope to God that they keep me in that 1990 [series]," he admitted. "Jack Thorne and Shane [Meadows] are brilliant writers."
Socha also praised the original four-part series, calling it "something really special".
"When we were doing it, we just saw a brilliant script," he said. "We were just really lucky to have the opportunity to work with Shane and be a part of such natural, beautiful work."
Socha's co-star Vicky McClure previously admitted that there is "definitely talk" of producing the sequel.
