In the TV series House M.D., who plays the diagnostician Gregory House?

Hugh Laurie plays the diagnostician Gregory House in House M.D.

Laurie, an English actor, portrayed the brilliant but abrasive physician throughout the series. The role required him to perform an American accent, which helped make House sound distinct from Laurie's real speaking voice. His performance became the central feature of the medical drama, combining sarcasm, physical pain, deductive reasoning, and emotional distance.

Before House M.D., Laurie was widely known in Britain for comedy, including A Bit of Fry & Laurie and Blackadder. House M.D. made him a major international television star and earned him multiple award nominations, including wins at the Golden Globes.

A common mix-up is confusing the actor with the character: Gregory House is fictional, while Hugh Laurie is the performer. Laurie also played the lead in the later series Chance and appeared in films such as Sense and Sensibility.
