The Perfect Storm
The following weapons were used in the film The Perfect Storm:
Mossberg 500 Cruiser
Captain of the Andrea Gail Billy Tyne (George Clooney) uses a Mossberg 500 Cruiser shotgun to kill a shark when the rough sea throws it onboard and it bites Bobby Shatford (Mark Wahlberg) in the leg. Interestingly, it seems to switch from having a standard magazine tube to a high-capacity magazine between shots.
