Season two hit the streaming platform today, and Tom Hopper (Luther) and Robert Sheehan (Klaus) both told LADbible they were up for a trilogy, to bring the show in line with the three graphic novels written by My Chemical Romance frontman Gerard Way.
Hopper said: "Yeah, we love hanging around in this world. It's a lot of fun. And we all love working with each other. It's quite a gift to have the kind of show we have really because we have a showrunner [Steve Blackman] who's very collaborative.
"So it's very freeing as an actor. And it's great to have that source material to see where we could go, what we could do. As you saw from the first two seasons, there are influences from the comic, absolutely.
"But it also allows us to deviate from that structure a little bit. And I love seeing where Steve Blackman's mind can go past the comics, how broad he can take it. And what you can put these characters through ultimately.
"He has an amazing ability to individually put us all through hell and back in a very unique way. So yeah, I'd love to go back and do a bunch more of these.
"That's the fun part of it - an element of assuming that the story continues until you're told that it's not going to continue. You're always keeping it alive in your head as an actor because you don't like kill off a character until it's kind of done.
"You're always seeing or where they could go, what could happen. You're trying to keep it alive until they say 'we're pulling the plug'."
Sheehan said: "I'd love to do one. A graphic novel is pure comic escapism. There's oodles of time travel, and powers, and it's very, very earthly - whereas I think Steve's intuition is always to bring it back and make it more make the characters' journeys.
"Steve started talking about, well, maybe one more. You're always talking about seasons, you know, from season one, you're always talking about where the show could go. So yeah, I mean, there's always conversations happening about future seasons.
"I'm always hatching pipe dreams and sending emails to Steve."
The Umbrella Academy season two is on Netflix now.
