Released on November 18, 2007, to capitalize on I Am Legend (2007), which was released on December 14, 2007.
The car that Renchard is driving at the beginning of the movie, as well as the convertible that he and Brianna take from the parking garage, are 1975 Oldsmobile Omegas, obviously a reference to the tile of the movie. This model was built from 1973-79 and was not produced as a convertible; the "convertible" shown here is obviously a hardtop with its roof cut off.
The car he drives is a 1976 Oldsmobile Omega.
As with numerous other low budget horror films, in this movie several times occurs a variation of Mike Oldfield's Tubular Bells, from The Exorcist.
