Had THE GRADUATE been made in the 1950s instead of the 1960s, Barbara Stanwyck could have played the absolute living hell out of that Mrs. Robinson role. Can you just imagine? Yep. Barbara Stanwcyk would have totally rocked as Mrs. Robinson in THE GRADUATE. That's my opinion.
In a famous frame with Dustin Hoffman's character, the professor noted how Nichols added to the eroticism of the scene with the way a lighting fixture is shot. Look on the upper middle of the frame. The shadow of the hotel room light fixture looks like a sex toy -- which is what Benjamin (Hoffman) basically is to the carnal Mrs. Robinson.
Stanwyck was great in DOUBLE INDEMNITY. Had THE GRADUATE been made in the 1950s, she could've been great in that too.
