Backed by the Pentagon: Or the LAPD, rather. Actual SWAT officers appeared in the opening scenes of the movie, most of them in delivering the hotline between the negotiators and the bank robbers.
Hey, It's That Guy!: Dominick Lombardozzi (Herc in The Wire) makes an appearance as Montel's bodyguard, as does Reg E. Cathy (Norman Wilson in The Wire) as Lieutenant Velasquez. The film was also directed by Clark Johnson, a filmmaker/actor who played Gus Haynes in The Wire.
