Although the show usually shoots on film, this season finale was shot on HD video using a Canon EOS 5D Mark II camera.
Opening titles are not used for this episode.
First episode without Jennifer Morrison in the credits.
House references Fire Marshall Bill, a recurring character played by Jim Carrey on the show In Living Color.
The watch House wears through most of this season is likely a Casio Sea Pathfinder watch. It's been the same through most of season 6 and fits with the overarching theme of the narrative.
