Stranger Things star Finn Wolfhard made a surprise guest appearance in the recently released revival series Malcolm in the Middle: Life's Still Unfair. Who did he play?
After two decades, Malcolm in the Middle is back on our screens with the four-episode revival series that reunites almost the entire main cast from the original series. Fans have been looking forward to seeing what they have in store for the return and whether they have some surprises in store.
Who Did Finn Wolfhard Play in Malcolm in the Middle: Life's Still Unfair?
Finn Wolfhard appeared in the final episode of Malcolm in the Middle: Life's Still Unfair as the event planner for Lois and Hal's anniversary party. His appearance came as a surprise since his guest role was not announced before the release.
The Stranger Things star is a fan of the original series, and his appearance came after his agent requested that the actor visit the set of the revival last year.
“His agent called us and said, ‘Can Finn visit the set?’ We go, ‘S***, yeah.' He loves the show, he’s such a big fan of the show, and we’re like, ‘Well, there’s a part we haven’t cast yet. Does he wanna do that? I mean, it’s a small part.’ And he said, ‘F*** yeah, he wants to do it.’ And we were like, ‘F*** yeah, we want you to come, that’d be awesome,'" showrunner Linwood Boomer explained to Deadline.
The cast and crew had a great time working with Wolfhard when he filmed his scenes in the series.
"He was so great. He’s so charming, It’s so fun to watch him do comedy. He was so cute with Lois, Jane Kaczmarek," executive producer Tracy Katsky said.
"He was standing there, and he kept forgetting to deliver his lines, because he was just so overwhelmed that Lois was screaming at him, and he’d kind of go, ‘Oh wait, I have to act. OK, OK.’ It was so cute."
