The Green Hornet (2011)
The following weapons were used in the film The Green Hornet:
Double-Barreled Handgun (Beretta 92FS)
Chudnofsky (Christoph Waltz) carries a handgun with twin Desert Eagle-style slides and barrels. It would most likely be impossible to make a remotely useful weapon which worked like the one shown (issues such as how the rounds would feed and eject from the guns are just a few of the problems); even in the movie, Chudnofsky mentions when confronting Danny "Crystal" Clear (James Franco) that the gun was "very difficult to make". It appears that the double barreled mockup was built around a modified Beretta 92FS. This was presumably done to show muzzle flashes coming from the gun (and presumably to cut down on costly CGI shots). The handgun is also seen being able to swivel out (presumably for a wider range of fire, something not possible at all in any practical weapon).
Beretta 92FS Inox
Danny "Crystal" Clear's henchmen are briefly seen drawing Beretta 92FS Inox handguns.

Kato's Hidden Gun Cache
In a deleted scene, Kato reveals a hidden gun cache to Britt Reid (Seth Rogen), aka "The Green Hornet". Among the weapons is an MP7, an MP5SD, an HK416, a P90, a TEC-9, an AKMSU, and a G36. Plus 2 possible SIG-Sauer handguns, and a UMP.40 or .45 above the HK416 and what appears to be a shotgun standing vertical. Along with a vertical M16 variant. 1 more, a Micro Uzi above the handguns.
