Samuel Noel "Sam" Strachan is a fictional character in the BBC medical drama Holby City, portrayed by actor Tom Chambers. 

Time at Holby City Hospital (2006-2008)

The character first appeared on-screen on 3 January 2006, in episode "Mother Love" - series 8, episode 12 of the programme. Chambers was cast in the role after sending a video of himself performing a Fred Astaire dance routine to over 800 television producers, and piquing the interest of BBC Casting Director Julie Harkin. Although he originally auditioned for only a minor role in the show, he was later asked back to audition for the newly created role of major character Sam Strachan.

Sam's initial function in the show was that of hospital Lothario – romancing and fathering the child of his boss, Connie Beauchamp, as well as engaging in relationships with Ward Sisters Chrissie Williams and Faye Morton, SHO Maddy Young, and Staff Nurse Zoe Foxe. However, he was taken on a redemptive path and was seen to change his philandering ways after being diagnosed with Non-Hodgkin lymphoma stage three, with just a 40% survival rate.

The character has proven highly popular with fans of the show, being voted in 2006 'Favourite Newcomer' of the series, and in 2007 'Favourite All-Time Male' within the show. However, in October 2007, the character also came under heavy criticism by drinks industry body the Portman Group, resulting from an incident of on-screen binge drinking, broadcast without showing any negative effects, which the group lambasted as "highly irresponsible."
