Are Tierney and Cook's characters gay lovers?
Did you notice the scene where we first see Lawrence Tierney's roomate, played by Elisha Cook Jr? There's only one bed in the room...with two pillows...and they both lie down on it...kind of weird. In old movies this kind of thing has to be hinted at delicately. And Cook's character, who has been his "roommate" for 5 years, seems to have an inexplicably strong attachment for him, helping him cover up murders, and trying to murder others to cover it up.
(his feelings don't seem to have been very well reciprocated, to say the least).
Tierney's character, at least, had been in prison; I get they feeling they were "prison buddies"; probably the Cook character was his "bitch". Of course, Tierney at least seems to like the women plenty as well.
