La Brea Star Eoin Macken Teases Big Season 2 Reveals

The season 1 finale of NBC’s time-traveling action drama La Brea gave us a lot of revelations as well as more than one cliffhanger. Eoin Macken’s character, Gavin Harris, filled everyone up. SYFY WIRE had the chance to speak with Macken about his character’s journey in Season 1, and he gave some hints as to what Gavin may be going through in the upcoming second season.

Read on for this discussion, but be warned!

*** Major spoilers for the first season of La Brea await us! ***

So let’s talk about the Season 1 ending – we learned a lot about Gavin in the finale, specifically that he’s actually the young boy Isaiah in 10,000 BC. That’s a pretty big reveal – when did you know this secret yourself?

I didn’t know that from the start. Something [showrunner David Applebaum] actually, what’s kind of funny is that we don’t really know what’s going on until we have the scripts because the characters don’t really know what’s going on either.

So the Isaiah-Gavin twist wasn’t something I was aware of until maybe a few episodes before that, which was interesting because as a character and as an individual I didn’t know not really why i had all these visions and so on. When we got the scripts and I found out I was like, “Okay, that makes sense.”

This revelation is obviously a big surprise for Gavin – how does your character deal with this knowledge in Season 2, especially since he’s back in 10,000 BC?

It’s interesting because I met the young actor who plays Isaiah, his name is Diesel and he’s very nice, and I only met him towards the very end of season 1 because we were on different shooting blocks and that we were shooting during COVID. When I met him, I said, ‘You’re playing young Gavin and he’s like, ‘No, you’re playing old me. I liked it, I liked the attitude.

But I think what’s interesting is that when Gavin goes back to 10,000 BC, he feels more comfortable there because he grew up there as a kid. And there are elements of things that he instinctively remembers growing up there and so he fits in a little faster than everyone else. There are little bits there in terms of how to survive that he remembers from his childhood.

David Applebaum said in an interview that Gavin’s trip to 10,000 BC from Seattle to Los Angeles is one of the “great pleasures” of season 2. I don’t know if your character would say the same, and I wonder if you could tease more of what Gavin is going through on this journey.

I’m sure it was great fun for everyone watching. [Laughs.] We had a rough time but it was great – we are surrounded by creatures and walking through the forest was no picnic. I think what’s most important, other than the action-adventure part, is that Gavin is out there with his daughter with him and that heightens everything, including being around creatures.

I’m glad you mentioned the creatures because the juggernaut in the season 1 finale was very impressive. I hope there will be more behemoths in season 2.

There’s some really cool stuff like that in Season 2.

Great! And, I imagine for you as an actor, shooting in 10,000 BC was different from shooting in 2021, which was the time period Gavin was in for Season 1.

It was really very liberating. I’ve always been a bit jealous of anyone who got to play in the forests and jungles of Australia. I dig all of this because it just appeals to your childhood sensibility of being an adventurer in the forest and going into the unknown. So I mean, I got a kick out of it. It was really hard physical work and time was always a thing, but honestly I enjoyed it.

Were there any big stunts you had to do?

Oh yes, we have plenty. And that’s also what I appreciate, because last season was more cerebral and I tried to understand what was going on. So this season has a lot more action and adventure. And they really upped the ante in terms of the size of the creatures and what they can do and so on. Each episode has become a real action adventure, which I appreciate.

Another mystery that was dropped in season 1 was this modern building that we saw in 10,000 BC I know you can’t say anything about that explicitly but is there anything like that level of revelation what will we see in season 2?

Yes. There’s some massive new twists going through this season, which – like I said – gets really fun because I really don’t know what’s going to happen. We have maybe three episodes left to shoot, and I couldn’t tell you what’s going to happen in any of them. But there are three or four big massive twists that happen, especially in the first half of Season 2 that threw me for a loop.

Do you think fans will also be happy to get answers to the series’ existing mysteries?

I think they will be more than satisfied. This year’s entire show has gotten bigger and grander, but all the twists have gotten more succinct and got even crazier and layered. I was really excited to read the scripts this year, and it’s been really exciting to play it all. So I think the fans are going to love it – I think La Brea last year was finding out what it was because he was still establishing how crazy the situation was. And now that that’s sort of settled, the show can really grow and grow, and that’s incredibly exciting.

This interview has been lightly edited and condensed for clarity. La Brea returns for its second season on NBC on Tuesday, September 27 at 9 p.m. EST. New episodes will be available to stream exclusively on Peacock the day after they air.
