Hollywood Homicide is a 2003 action comedy starring Harrison Ford as LAPD Detective Joe Gavilan, who has to juggle his work as a homicide detective with his sideline job as a real estate broker. While breaking in a rookie partner (Josh Hartnett), Gavilan tries to solve a multiple homicide involving musicians in the rap industry. The film was directed by Ron Shelton (Dark Blue) and was co-written by Robert Souza, a former LAPD homicide detective.
The following guns were used in the film Hollywood Homicide:
LAPD Det. Sgt. Joe Gavilan (Harrison Ford) carries a Smith & Wesson 4566 as his sidearm throughout the film. This is quite accurate as the S&W 4566 is actually one of several .45 ACP pistols authorized for carry in Los Angeles.
Beretta 92FS
Det. K.C. Calden (Josh Hartnett) keeps a Beretta 92FS as his sidearm throughout the film. LAPD officers are also seen with Berettas, one of which is snatched by a criminal being arrested, who fires it around the police parking lot with his hands cuffed behind his back. K.C counts the shots fired and goes to jump him after 15 shots (which, if closely counted, is the full 16 shots), only to be shown by Joe that the gun still has "One in the 'spout'" (meaning one still loaded in the chamber).
Heckler & Koch MP5A3
Several gangsters during the beginning of the film mow down 4 rappers with H&K MP5A3 submachine guns fitted with RIS foregrips and Aimpoint Comp-M2 reflex sights. They look to have Navy style trigger groups.
Glock 17
Danny Broome (James MacDonald) is seen with a chrome slide Glock 17 2nd Generation which he shows to Joe and K.C. in an attempt to intimidate them. Antoine Sartain (Isaiah Washington) is later seen using the same Glock to fire at Joe as he pursues him.
Leroy Wasley (Dwight Yoakam) is armed with a Walther PPK/S, which he fires at Joe and uses to hold up K.C. before he acts his way out of being killed and manages to get a confession from him claiming he murdered his dad.
