What movie was Hansen watching?
When he said, "She's very appealing" to Philipe, then asked him to shut the door on his way out?
That's Catherine Zeta-Jones, and I believe the film was Entrapment.
Hanssen used to masturbate in his office. Did you see expression on O'Neill's (Phillippe's) face?
"I'd never ask you to trust me. It's the cry of a guilty soul."
