Jonah gives Tom what-for, which is all the churl deserves for violating the dress code!
Like any proper spaghetti western, Massacre Time is good and violent, though you shouldn't expect violence or bloodshed on the level of Fulci's zombie films. The action is well staged and gives Fulci opportunities to show some style. In once scene Nero and Hiton hole up in a ruined house awaiting a parley with Scott. Fulci films them setting up shop through a broken wall and an empty window frame. Later, he employs a frame within a frame as Nero fires his gun in one shot, and in the next we look through a window next to Hilton and see a rider fall from his horse. In the same sequence Hilton gets a nice bit of business that demonstrates the "show, don't tell" principle. Nero suspects him of having shot someone he shouldn't have and knocks him around a bit. It won't do for Hilton to just say, "I didn't do it!" Instead, he proves his case by opening his weapon and letting the bullets drop, one by one, until we see six on the ground and know he's innocent -- this time.
