Simonson's murder---an unusually brutal scene for 1973?
When Simonson is murdered---the assassin does a two-arm full arc overhead swing and buries the crowbar in Simonson's head (including a loud "whomp!" as it goes into his skull). Then there is a sharp backwards yank (the implication is the crowbar was buried in Simonson's head), so that the killer can immediately wind-up for another devastating blow!
Watching this last night on my big screen tv, I am thinking this all must have been shockingly graphic for audiences back in 1973. It certainly made me wince.
