When Cyril Hardeen offers to fight Eliot in hand-to-hand combat, he rolls up his shirtsleeves. First he rolls up the shirtsleeve of his left arm, then the shirtsleeve of his right arm. When he says "I think a great deal of Edith." we can see him unbuttoning the shirtsleeve of his right arm again and rolling it up, even though he had just done that.
At the 4:00 mark Enid is sitting sideways with one hand holding the other at the top of the couch. In the very next shot her left arm is straight down along her side.
