Who Played Nancy Casey On Chicago Fire?

The actor behind Nancy Casey is the inimitable Kathleen Quinlan. And if you thought her work on "Chicago Fire" was of the scene-stealing sort, that's pretty much par for the course for Quinlan, as she's been stealing scenes in Hollywood for a few decades now. Even if you don't know Quinlan by name, you've almost certainly seen her at work over the years.

Quinlan began her big screen career in high fashion, claiming a small, but memorable role at age 17 in George Lucas' iconic period drama, "American Graffiti." She's gone on to appear in some of the most notable films and television series of the ensuing decades, earning a reputation for portraying strong, yet grounded female characters. Some of the actor's most notable credits include "I Never Promised You a Rose Garden," "Airport '77," "Twilight Zone: The Movie," "The Doors," "Event Horizon," and the 2006 remake of "The Hills Have Eyes." 

Fans of Ron Howard's star-studded, Oscar-winning historical drama, "Apollo 13," will forever identify Quinlan for her role as Marilyn Lovell, the steadfast wife of imperiled astronaut Jim Lovell (Tom Hanks). Quinlan earned an Academy Award nomination for her work in the film, which remains a legit career highlight. More recently, Quinlan made a memorable one-off appearance on "How to Get Away With Murder," and turned up in Hulu's underrated Marvel series, "Runaways."
