Great scene, including the S&W M76. Actually the shotgun was a High Standard.My personal fave is from Director Sam Peckinpah again, three years later, in 1972. The Getaway, with Steve McQueen and Ali McGraw. The shootout with McQueen coming down the stairs, floor by floor, of the flophouse hotel, is a classic. It's been a while since I've viewed the movie, but McQueen is ably utilizing a riot shotgun, an Ithaca 37, I believe.
Actually, the hero Phil Moskowitz and the villain Wing Fat are looking for the recipe for the perfect egg salad (yechhh!).The hero is shooting at the bad guys and he says, "Watch me shoot 8 guys with 6 shots." That movie was hilarious. I think the dubbed dialogue had to do with trying to find a recipe for meatballs.
