as St. Elsewhere, ER, Sports Night, and The West Wing. The technique involves the use of tracking shots, showing two or more characters walking between locations while talking. Executive producer Katie Jacobs said that the show frequently uses the technique because "when you put a scene on the move, it's a ... way of creating an urgency and an intensity". She noted the significance of "the fact that Hugh Laurie spans 6'2" and is taller than everybody else because it certainly makes those walk-and-talks pop". Nancy Franklin of The New Yorker described the show's "cool, Fantastic Voyage–like special effects of patients' innards. I'll bet you didn't know that when your kidneys shut down they sound like bubble wrap popping."

The pilot episode was filmed in Vancouver; primary photography for all subsequent episodes took place on the Fox lot in Century City, Los Angeles. Bryan Singer chose the hospital near his hometown, West Windsor, New Jersey, as the show's fictional setting.

Part of Houses sixth season was filmed at the abandoned Greystone Park Psychiatric Hospital, in Parsippany-Troy Hills, New Jersey, as the fictional Mayfield Psychiatric Hospital. Opening sequence The opening sequence begins with an MRI of a head with an image of the boxed "H" from the logo (the international symbol for hospital) in the foreground. This is then overlaid with an image of Dr. House's face taken from the pilot episode with the show's full title appearing across his face. House's head then fades and the show's title is underlined and has the "M.D." appear next to it, producing the entire logo of the show. This was the full extent of the title sequence in the pilot episode. All subsequent episodes contain a longer sequence including
