Maybe these deleted scenes (including all the ones from JP1) were lost in the Universal backlot fires...
"The most damage was done on June 1, 2008 when a three alarm fire broke out on the backlot of Universal Studios. The fire started when a worker using an acetylene torch for welding accidentally let it set fire to the surroundings. The Los Angeles County Fire Department had reported that Brownstone Street, New York Street, New England Street, the King Kong attraction, some structures that make up Courthouse Square, and the Video Vault had burned down (not to be confused with the actual Film Vault, The Video Vault contains the duplicates of the films). Aerial news footage showed the miraculous survival of the Courthouse building survived the fire (for a third time) with only the west side of it being slightly charred. Over 516 firefighters from various local fire departments, as well as two helicopters dropping water, had responded to the fire. Fourteen firefighters and three Los Angeles County sheriffs' deputies sustained minor injuries. The fire was finally put out after 12 hours, since firefighters encountered low water pressure."
