Death to Smoochy is a 2002 black comedy starring Robin Williams, Edward Norton, Danny DeVito, Catherine Keener and Jon Stewart, directed by DeVito. The film tanked at the box office, making back less than twenty percent of its budget and earning Robin Williams a Razzie nomination for Worst Supporting Actor. The film was the second of three "dark" films released by Williams within a space of four months in 2002, between One Hour Photo and Insomnia (2002), though this is easily the most light-hearted of the three.
The following weapons were used in the film Death to Smoochy:
Burke Bennett (Danny DeVito) gives his client Sheldon Mopes/Smoochy (Edward Norton) a gift, which turns out to be a stainless Ruger SP101. Nora Wells (Catherine Keener) takes it after it is knocked out of Sheldon's hand in the end.
Smith & Wesson Model 36
Rainbow Randolph (Robin Williams) confronts Sheldon and Nora in Sheldon's corporate penthouse with a Smith & Wesson Model 36. His Model 36 is an older version with flat cylinder latch and is fitted with Pachmayr grips. Sheldon later takes it away from him. Burke later confronts Sheldon with a S&W Model 36 of his own, but Sheldon takes that one as well.
M1911A1
Mitch the thug (Richard Cocchiaro) is seen using a stainless M1911A1 variant, possibly a commercial Colt Government Model.
Beretta 92FS Inox
The "parents" (Craig Eldridge and Judy White) at Rainbow Randolph's sting operation draw Beretta 92FS Inox pistols.
An FBI agent at the sting is seen with a SIG-Sauer P228.
Submachine Guns
Colt 9mm SMG (RO635)
A SWAT team member is seen with what appears to be a Colt 9mm SMG (RO635). The barrel length makes it likely a Colt SMG, however the magazine is not seen so this is not a positive ID.
Heckler & Koch MP5
SWAT team members are seen with a Heckler & Koch MP5s. There's not enough detail to determine the variants of either gun in the shot, but one is equipped with a SureFire weaponlight forend.
