Actress Kelly Reilly

Kelly Reilly is an English actress who has made big splash in America. 

She plays Beth Dutton in the Paramount TV series "Yellowstone," about a family who owns the largest ranch in the lower 48 states. Beth is a financier who helps run the ranch but battles with personal demons.

Ms. Reilly got her start playing a role on the British television drama "Prime Suspect," which led to other small television roles.  Her breakthrough came in the 2008 film Eden Lake, a horror movie in which she played a nursery school teacher who makes a journey to a lake in the English countryside.  This led to, among other things, two Sherlock Holmes moves as Dr. Watson's wife,  and as a heroin addict in Robert Zemeckis' 2012 airline thriller Flight, starring Denzel Washington. 

Ms. Reilly is no stranger to American television, by the way.  In 2014 she starred the ABC series "Black Box" as Catherine Black, a famed neuroscientist who studies and solves issues concerning the human brain while trying to keep private her own bipolar disorder from the world.

"Black Box" was not a hit but "Yellowstone," having just been renewed for a second season, should ensure that Kelly Reilly will be around a little longer this time.
