Movies are never realistic. I wouldn't mind knowing what movie it is. Are you sure it wasn't a Remington or Colt? I've seen a few movies with those, mostly westerns though. I like the Circuit Judge but it's probably not the most durable or practice gun out there. I have tried to deer hunt with it and used to keep it loaded for around the house.
There's an Internet movie firearms database. Perhaps the information can be found there. This is an awfully thin connection for "firearms-related, though.
