The original Director's Cut focused on the Annalynne McCord character based on the original script rather than the added role of the Russian mistress played by Kamalya Zahoor. Unbeknownst to the director or the rest of the cast, producer Jeff Most had guaranteed Zahoor's wife a major supporting role, produced and directed a separate music video with her singing in the club, and even shot scenes that were never scripted under the title "Scene X" during principal photography, which they later edited into the final cut.
Stephen Dorff and James Woods previously appeared in In Love and War (1987), which was Dorff's first film role.
Tommy Flanagan co-starred with Kim Coates in Fox's outlaw biker series "Sons of Anarchy" as 'Chibbs' & 'Tig', respectively. Coates later starred in the similarly titled fantasy action film "Officer Downe" (2016).
James Woods, Stephen Dorff, David Boreanaz and Elizabeth Rohm have one in thing in common. They all starred in either a movie or a TV series about vampires. Dorff played vampiric criminal Deacon Frost in BLADE. Boreanaz played the titular vampire in the BTVS spin-off ANGEL (with Ms. Rohm guest-starring as LAPD Detective Kate Lockley). And Woods played vampire-hunting mercenary Jack Crowe in John Carpenter's VAMPIRE$.
