Two big streaming shows just got a lot more interesting, and the announcements landed on the very same day.
Sam Heughan is leaving behind his kilt for a new role, joining Viola Davis in Paramount+'s upcoming thriller series Ascent. The news broke on October 22, 2026, the same day Netflix confirmed four new cast members for The Watcher Season 2, which starts filming in New York this fall.

Sam Heughan Ascent Paramount+ Role Revealed
Heughan will play a character named Conal, one of the top agents working at a company called Ascent Ventures. The official description calls him lethally charming and a natural chameleon. He gets things done through social cunning and ruthlessness, and he genuinely enjoys finishing a job. It's a sharp turn from his long run as Jamie Fraser on Outlander, trading swords and Scottish hills for boardrooms and corporate secrets.
Viola Davis plays Catriona Vail, described as an elite corporate fixer. Her clients are worth billions, and her skills have made her impossible to replace. But the show's real hook is personal. Catriona has to use those same ruthless abilities to protect her own estranged daughter when danger comes knocking. Davis is also executive producing the series, adding another layer to her already packed resume as an EGOT winner.

Inside The World Of Global Corporate Crisis Management
Ascent is built around a world most thrillers skip over: corporate crisis and damage control. Instead of cops chasing criminals, this show follows fixers who clean up messes for the ultra-wealthy. John Logan created the series and is also serving as showrunner, giving it a clear creative vision from the start.
The pairing of Davis and Heughan sets up an obvious tension. One is the seasoned fixer who built an empire on control and secrecy. The other is a slick operative who thrives on manipulation. Putting them in the same story, especially with a family crisis driving the plot, gives the series an emotional core beneath all the corporate scheming.
Paramount+ hasn't released a premiere date yet. What we do know is that production is expected to begin in Los Angeles sometime in 2027. That means fans will need to wait a while before seeing Heughan and Davis share the screen, but the casting news alone has already generated buzz across entertainment outlets.
The Watcher Season 2 Adds Riverdale And Wednesday Stars
While Paramount+ was making headlines with Ascent, Netflix was busy announcing its own casting update. The Watcher, Ryan Murphy's mystery thriller about the Brannock family, is adding four new series regulars ahead of Season 2. Madelaine Petsch, known for playing Cheryl Blossom on Riverdale, is joining the cast along with Evan Adams, Owen Painter and Quintessa Swindell.
Petsch isn't new to Murphy's world. She previously appeared in American Horror Story, so this marks her second collaboration with the producer. Painter has a recent credit on Wednesday, while Swindell is recognized for roles in Prime Target and Black Adam. None of their character names or story roles have been revealed yet, so exactly how they fit into the Brannock mystery remains a mystery of its own.
The returning cast includes Naomi Watts and Bobby Cannavale as the original leads, along with Margo Martindale and Isabel Gravitt. Season 1 ended without clear answers about who was actually watching the Brannock family, and Netflix says Season 2 will pick up in the aftermath of that ambiguous finale. Production begins in New York this fall, putting the show on a faster track than Ascent.
What These Casting Moves Mean For Both Shows
These two announcements say a lot about where streaming thrillers are headed right now. Paramount+ is leaning on star power, pairing an Oscar winner with a global fan favorite to build buzz for a brand-new concept. Ascent doesn't have built-in name recognition like a book adaptation or a remake, so the cast itself is doing the heavy lifting to generate interest.
Netflix, on the other hand, is expanding something that already has an audience. The Watcher drew big numbers in its first season thanks to its creepy, true-crime-adjacent premise. Adding four recognizable younger actors could help pull in viewers who weren't around for Season 1, while keeping original fans hooked with Watts and Cannavale still in the picture.
Both projects now carry real anticipation, but for different reasons. Ascent is the mystery box, a fresh story with two major stars and no footage yet. The Watcher is the known commodity getting fresh blood injected into its ensemble. Neither has a release date locked in, but the production timelines give fans something concrete to track over the next year.
What Comes Next For Ascent And The Watcher
For now, Paramount+ viewers will have to be patient. Filming doesn't start until 2027, and there's no word yet on episode count, additional cast members, or a trailer. Expect more details to trickle out as production dates get closer.
The Watcher moves faster. With filming set for this fall in New York, a Season 2 release could realistically land sometime in 2027 as well, though Netflix hasn't confirmed a window. Viewers can expect more casting reveals and plot teasers as the shoot gets underway, especially once the new characters' identities become public.
