Last month, we reported that actress Sharon Stone was replacing Uma Thurman in the action comedy American Ultra, which is currently in production. Today, Lionsgate announced that Nashville star Connie Britton is stepping in for Sharon Stone to play Victoria Lassetter, the head of a government program who tracks down a sleeper agent, played by Jesse Eisenberg. Take a look at the official press release for more information.

Four-time Emmy-nominated Connie Britton will appear as Victoria Lasseter in Lionsgate's action comedy film American Ultra. The film started production earlier this month.

Britton, who has received accolades for her work in television and film, earned Emmy and Golden Globe nominations for Best Actress for her role as Rayna Jaymes on Lionsgate and ABC Studios' critically-acclaimed drama Nashville, currently in its second season on ABC. After stand-out roles on series such as Spin City, 24 and The West Wing, she starred on the acclaimed series Friday Night Lights, created by Peter Berg, for which she received Emmy nominations in 2010 and 2011. She also starred in the film of the same name, opposite Billy Bob Thornton. Britton received a Best Actress Emmy nomination for her role as the female lead in American Horror Story, Ryan Murphy and Brad Falchuk's Emmy-nominated miniseries. Britton's other feature film credits include the upcoming release This Is Where I Leave You opposite Jason Bateman, Tina Fey and Adam Driver, and she was previously seen in The to Do List.

Directed by Nima Nourizadeh (Project X) and written by Max Landis (Chronicle and the upcoming Frankenstein), American Ultra stars Jesse Eisenberg, Kristen Stewart, Topher Grace, Tony Hale, John Leguizamo, Bill Pullman and Walton Goggins. A PalmStar/Likely Story/Circle of Confusion production, the film is produced by Anthony Bregman (Begin Again and Eternal Sunshine of the Spotless Mind), Kevin Scott Frakes, Raj Brinder Singh, David Alpert (The Walking Dead) and Britton Rizzio, with Ray Angelic as executive producer.

American Ultra is a fast-paced action comedy about Mike (Eisenberg), a seemingly hapless and unmotivated stoner whose small-town life with his live-in girlfriend, Phoebe (Stewart), is suddenly turned upside down. Unbeknownst to him, Mike is actually a highly trained, lethal sleeper agent in a government program created by Victoria Lasseter (Britton). In the blink of an eye, as his secret past comes back to haunt him, Mike is thrust into the middle of a deadly operation and is forced to summon his inner action-hero in order to survive.
