- Lauren Cohan, Mark O'Brien, and Mia Tomlinson joined Prime Video's "Stillwater" as series regulars opposite lead Ben Hardy, who plays ex-con Daniel West.
- Stillwater is a horror thriller adapting Chip Zdarsky and Ramón K Pérez's Skybound graphic novel, produced by Warner Bros. Television, Berlanti Productions, and Skybound Entertainment.
- Cohan plays Catherine "Cat" Keegan, a former homecoming queen whose small-town charm has sharpened through decades of grudges; she is deeply loyal to husband Ted Keegan, a sheriff's deputy played by O'Brien.
- O'Brien portrays Ted Keegan — a father, farmer, and military veteran who enforces Stillwater's strict policies, sometimes through violent means, while hiding a truth that could destroy his own family.
- Tomlinson plays Laura Quinn, Cat's younger sister and a spirited single mother who faced an impossible choice the day Stillwater changed overnight, altering her future and the town forever.
- Greg Berlanti and Carly Wray executive produce the eight-episode series; Wray co-wrote the pilot, and the series was ordered ahead of San Diego Comic-Con in July 2026.
Why it matters: Greg Berlanti expands his horror-thriller footprint at Prime Video with a Skybound graphic-novel adaptation built around an eight-episode order and a Comic-Con 2026 launch window, and the casting of Walking Dead's Lauren Cohan as a gun-toting, secret-keeping homecoming queen gives the show a recognizable genre-TV anchor. Tomlinson reunites with Hardy after The Conjuring: Last Rites, while O'Brien arrives off Peacock's The Copenhagen Test.
