Swan Song is an 8th season episode of House which first aired just before the series finale Everybody Dies on May 21, 2012. It was an hour-long retrospective on the entire series.

• Hugh Laurie notes that Allison Cameron almost always draped her lab coat over the back of her chair.
• Hugh Laurie recollects that Omar Epps often exhibited hypochondria during the show, becoming convinced that he had one of the diseases they discussed.
• Almost 100 canes were lost or broken during production.
• Although the medical instruments used on the show were real, most of the body parts and blood were faked.
• Over 5 million man-hours went into the making of the show, the equivalent of 566 man-years of labor.
• 4, 074 miles of film were used in production of the series.
• In medical jargon, "swan song" is a state of patient, when his condition gets better before resulting in death.
• Swan Song is also the title of an episode in Once Upon A Time (Season 5, Episode 11) which also stars Jennifer Morrison (Allison Cameron) as the main character of Emma Swan.

The character of House:

• From the beginning, the series creators realized the role of House was critical to the success of the series. Dozens of people auditioned for the role. When Bryan Singer saw Hugh Laurie's audition tape, he was impressed by Laurie's deep voice and his beard stubble (Laurie was in the middle of shooting Flight of the Phoenix in Namibia at the time). Singer was also relieved Laurie was American (which he wasn't - Singer was fooled by Laurie's pitch perfect accent) because he believed that a Brit could not both do an American accent and pronounce the medical jargon correctly at the same time.
• House was imagined from the beginning as being disabled. The original conception of the character had House in a wheelchair. However, the producers soon realized that would severely limit where the character could go (they tried it as an experiment in Needle in a Haystack). They then thought of a scar, but eventually settled on the cane. However, once they settled on a cane, they realized that when the character was walking in a tracking shot, in order for him to stand out properly against the other actors, he would have to be well above average height. Laurie's 6'2" height worked to his advantage.
