The 1990 Mazda Miata used in Dead of Knight (2009) is the same car used in Laughing Boy (2000) and Death and a Salesman (1995).
Completely by coincidence, Dan Braverman, who plays Detective Sutherland in Dead of Knight (2010), a movie about an ancient magical artifact which causes supernatural mayhem, also plays Big Al in Dylan Dog: Dead of Night (2010), a movie about an ancient magical artifact which causes supernatural mayhem. Additionally, and equally coincidentally, the male leads in both films are named Brandon.
