In the beginning, as Nelson plays his violin you can see a quiver on his back, the next scene it is gone.
When Ryan is in the hospital looking for the records room, two PA announcements are overheard. The first one is for Dr. Kimball. Dr. Kimball is a fictional character in the hit TV series The Fugitive who was charged with the murder of his wife and became a fugitive while trying to prove himself innocent. The second announcement is for Dr. Kevorkian to Mr. Simpson's room. In Naked Gun 33 1/3: The Final Insult, Nordberg, who was portrayed by O.J. Simpson, suggest that Leslie Nielsen be given Dr. Kevorkian's home phone number.
