Marsha Thomason is an English actress best known for her television roles as Nessa Holt in Las Vegas and as Naomi Dorrit on Lost.

She also starred as FBI agent Diana Berrigan in the comedy-drama police procedural television series White Collar.

Thomason starred opposite Eddie Murphy in Disney's ghostly Haunted Mansion and portrayed the female lead in the Miramax comedy My Baby's Daddy with Eddie Griffin.

She also starred with James Caan in NBC's hit series Las Vegas, as a sexy and ruthless pit boss known as the Ice Queen, and taunted the islanders in a multi-episode arc on ABC's Lost.

She also starred on the acclaimed CW dramedy Easy Money about a family of loan sharks, and immediately segued into a multi-episode arc on ABC Family's Make or Break It, which she simultaneously filmed alongside her role opposite Golden Globe winner James Franco on General Hospital.

Thomason began acting at age 12 when she joined the Oldham Theatre Workshop. What began as a hobby, soon evolved into a successful procession of British television series including the BBC's Burn It, Brazen Hussies with Julie Walters, Pie in the Sky and Playing the Field in which she starred as Shazza in the drama about a female soccer team.

Thomason also starred in ITV's popular series Where the Heart Is, as well as the network's Prime Suspect 5 alongside Helen Mirren.

She was first introduced to U.S. audiences as the heroic handmaiden opposite Martin Lawrence in Twentieth Century Fox's Black Knight in which she was able to exercise her native British and honed American accent.

With a steady string of credits, it is not surprising then that she received a 2002 Best Female Performance Award by Black Filmmakers Magazine.

Her stint in Channel 4's Love in the 21st Century from Red Productions (Queer As Folk), was followed by her April 2000 professional stage debut at London's renowned Royal Court Theatre as the lead in Breath Boom.

Additional film credits include Working Title's Long Time Dead with Lukas Haas, about a group of friends who unleash an evil force while playing with a Ouija Board; as well as the independent feature Pure opposite Keira Knightley for director Gilles MacKinnon (Hideous Kinky).

Thomason also starred in the British comedy film Caffeine and took a more dramatic turn in the gritty Nickel Children which is a film that recounts a story of child prostitution.

She also starred in David Arquette's The Tripper, the comedy feature L.A. Blues and the sequel to Into the Blue.

Thomason resides between London and Los Angeles.
