Britta DeVore is a Senior Author for Collider who has been known to dabble with Reality News as well.

Have you seen stories about 'Chucky,' 'Scream,' 'Buffy the Vampire Slayer,' 'The Boys,' 'Vanderpump Rules,' or any of 'The Real Housewives' franchises? That's probably a Britta DeVore-curated piece of art, and it sounds like you have great taste.

When she isn't sitting behind her laptop bringing readers her hot takes on upcoming projects or keeping the dream alive in the Senior News team, Britta can usually be found outside hiking or inside behind her drum set. She currently plays in two bands, Kid Midnight and Watergate, both based in Brooklyn. An obsessive traveler, Britta loves long road trips to the South West and has a soft spot in her heart for canyons, rivers, and forests.

She also has a tiny cat named Athena that she loves more than anything else in the world and is always happy for new brewery recs.

Swinging in to cure your winter blues, Prime Video’s upcoming series, The Gray House, blends a pulse-pounding espionage plot with the darkest and most dismal days of the Civil War to bring historical drama fans something completely new. Welcoming Emmy and Golden Globe winner, Mary-Louise Parker (The West Wing, Weeds), back to the episodic fold, the captivating tale of Union spies doing their best to undermine the South’s advances sets the stage for a binge-worthy arrival with all eight episodes hitting the platform on February 26. Today, as part of Collider’s Exclusive Preview event, where we’re showing off the most hotly anticipated titles to make their return in the approaching weeks, we’ve got a sneak peek of the project backed by producers Kevin Costner and Morgan Freeman.

Daisy Head (The Syndicate) is on a top-secret mission in our exclusive first look at The Gray House. Under the cover of night and a costume that conceals her true identity (complete with a fake mustache), her character slips into a party unnoticed and makes her way to the second floor. Upon her arrival upstairs, she finds the woman she'd been looking for but not the answers she was hoping for.

In addition to Parker and Head, Prime Video’s newest period drama also features the talents of a call sheet that includes Amethyst Davis (Happily Ever After), Ben Vereen (Jesus Christ Superstar), Keith David (The Thing), Paul Anderson (Peaky Blinders), Colin Morgan (Merlin), Ian Duff (We Own This City), Hannah James (Mercy Street), Christopher McDonald (Thelma & Louise), Robert Knepper (Prison Break), Catherine Garton (The War Between the Land and the Sea), Sam Trammell (True Blood) and more.

Meet the Creatives Behind ‘The Gray House’

Freeman will produce The Gray House under his Revelations Entertainment banner with his business partner, Lori McCreary, while Costner operates under his Territory Pictures. The title also hails from Paramount’s Republic Pictures and Leslie Greif’s Big Dreams Entertainment. Greif, who previously collaborated with Costner on Hatfields & McCoys, co-penned the Civil War-centered project alongside Darrell Fetty and John Sayles, with Roland Joffe (The Killing Fields) directing. Additionally, the soundtrack features an all-star lineup of musicians like Willie Nelson, Shania Twain, Killer Mike, Yolanda Adams, and more, adding their voices to the project, while Jon Bon Jovi holds co-writing credits for one of the title’s songs.
