• Laura Linney has officially joined the cast of HBO’s Lanterns, premiering August 16.
• Her role is being kept under wraps, but a teaser scene with Aaron Pierre’s John Stewart has fans theorizing she’s Carol Ferris.
• The series stars Kyle Chandler and Aaron Pierre as Hal Jordan and John Stewart, two Green Lanterns investigating a murder in the American heartland.
• Showrunner Chris Mundy revealed the show will run across two timelines — 2016 and 2026 — with Nathan Fillion’s Guy Gardner appearing multiple times.
• Linney’s casting was first reported in 2025 but only officially confirmed with Monday’s teaser drop.

Laura Linney is heading to the DC universe — and nobody’s saying who she’s playing. The acclaimed actress has officially joined the cast of HBO’s Lanterns, the highly anticipated Green Lantern series starring Aaron Pierre and Kyle Chandler, and a new teaser that dropped Monday gives fans just enough to start spinning theories.

The biggest one? She’s Carol Ferris.

In the teaser, Pierre’s John Stewart is mid-conversation with Linney’s character — clearly someone he trusts, someone whose opinion carries weight. “I was raised fearless, and I’ll do this better than he’s ever done it before,” John tells her. Her response is calm, assured: “Then go and get it, John Stewart.” It’s a brief exchange, but it’s loaded. And if John is looking for guidance on how to handle Hal Jordan — his mentor, his complicated predecessor — there aren’t many people in the DC mythology who know Hal better than Carol Ferris.

Created by John Broome and Gil Kane, Carol Ferris first appeared in DC Comics’ Showcase #22 and later as Star Sapphire in Green Lantern Vol. 2 #16. She’s been Hal Jordan’s on-again, off-again love interest, a skilled pilot in her own right, and — depending on the storyline — both an enemy and an ally of the Green Lantern Corps. The character has been voiced by Kari Wahlgren, Jennifer Hale, and Olivia d’Abo in animation, and was portrayed by Blake Lively opposite Ryan Reynolds in the 2011 film. If the Lanterns version of Carol is someone John turns to for perspective on Hal, that tracks perfectly with the show’s central dynamic.

DC Studios and HBO aren’t confirming anything yet. Linney’s casting was first reported back in 2025 but wasn’t officially announced until the new teaser made it impossible to ignore — her character appears prominently enough near the end of the preview that the announcement had to come out the same day.

What We Know About the Show Itself

Lanterns follows new recruit John Stewart and Lantern legend Hal Jordan — “two intergalactic cops drawn into a dark, earth-based mystery as they investigate a murder in the American heartland,” per the official logline. Showrunner Chris Mundy, who helmed True Detective: Night Country, co-created the series with Damon Lindelof (Watchmen) and Tom King (Supergirl). The pilot was co-written by all three.

In a new interview with Entertainment Weekly, Mundy revealed that the series actually runs across two separate timelines: 2016 and 2026. The 2016 story kicks off in Rushville, Nebraska, where a shooting has Hal convinced something alien is involved — though local Sheriff Kerry (Kelly Macdonald) isn’t buying it. A second mystery, set in 2026, will gradually converge with the first over the course of the eight-episode season.

“That becomes a second mystery that we know is down the road for us. So eventually two different mysteries get worked out over the course of the show,” Mundy explained. “It was less of a whodunnit as much as like, what happened and why? We think of this as a relationship show between John and Hal, and there’s a lot to unpack over the course of the eight episodes.”

The ten-year gap between those timelines is significant — the events of DC Studios’ Superman will have taken place within it. And Nathan Fillion’s Guy Gardner, described by Mundy as “fabulously obnoxious,” will appear “a few different times” across the series. Other Green Lanterns from the mythology get referenced, but won’t be showing up in person this season.

One of the more intriguing threads Mundy teased involves Ulrich Thomsen’s Sinestro, who trained Hal — who is now training John. That coaching tree, and what gets passed down through it (good and bad), is a central preoccupation of the show. “What did Hal take away from Sinestro that was good or bad? It brings up a lot of interesting worries,” Mundy said, carefully leaving open whether Sinestro will function as a straightforward villain or something more complicated.

Grounded, But Still Very Green

One criticism that surfaced after the first teaser was that it wasn’t green enough — not enough of the visual spectacle fans associate with Green Lantern. Mundy addressed it directly: “We could have put out a trailer that was tremendously green. So the fact that people are talking about it just means, to me, that they’re excited about the show. We have a lot of respect for the source material, otherwise we wouldn’t be doing this show. I think when people see it, it won’t be a controversy.”

The show’s aesthetic is intentionally grounded — shot practically on location rather than on green screen stages — but Mundy was clear that the constructs will be exactly what fans expect. “It’s a Green Lantern show, so there’s green,” he said. “Green Lantern fans will not feel like we’ve somehow made a brown show of their green comic at all.”

Director James Hawes, speaking with The Hollywood Reporter, pushed back a little on the True Detective comparisons that have followed the show since its announcement. “It is, in many ways, a buddy cop structure with travel in the story time, to and fro, that is really sophisticated,” he said. “I would also bring in ‘No Country for Old Men,’ ‘Fargo,’ and things that have that Americana heart to them. There’s a wry humor, and so there definitely is more wit and humor than there is in ‘True Detective.'”

Hawes was equally enthusiastic about Pierre, who he said won the role in the room. “He has such a magnificent presence. He feels so forceful, so cool, so understated,” the director said. Mundy echoed that in a separate interview with Men’s Health, describing what makes Pierre’s John Stewart so compelling: “He’s big. He’s an intimidating presence just physically. But there’s a softness to him, too. There’s a thoughtfulness. You can’t teach that.”

Linney’s Impressive Track Record

Whoever Linney is playing, she brings serious weight to the role. Best known to TV audiences as Wendy Byrde across all four seasons of Netflix’s Ozark — a performance that earned her three Emmy nominations for drama actress alone — Linney has also won Emmys for Wild Iris, The Big C, and the HBO miniseries John Adams. She’s a three-time Oscar nominee for You Can Count on Me, Kinsey, and The Savages. She most recently appeared opposite Kevin Kline in the MGM+ series American Classic.

Her track record with prestige television — particularly HBO — makes the casting feel like a statement. This is not a cameo. This is a character who matters.

Lanterns premieres August 16 on HBO and Max. The full cast also includes Kelly Macdonald, Garret Dillahunt, Poorna Jagannathan, Jason Ritter, J. Alphonse Nicholson, and Jasmine Cephas Jones.

“Then go and get it, John Stewart.” Whoever she’s playing, Linney already sounds like someone you don’t argue with.
