If you are a true connoisseur of cringe, see if you can find "The Eiger Sanction" with Clint Eastwood and George Kennedy. There's a part in that flick where Clint Eastwood's character pretends to be a gay-coded deliveryman with a package of dental floss. "What am I gonna do with this boxth of floth?" Unforgettably bad but mostly unforgettable :)

I love it when an actor has to play at being a bad actor. It really highlights their craft.

Harrison Ford is a great actor, Deckard is not. It's Deckard that is failing to be convincing in that scene, not Ford.

That's because Deckard is lying to her (poorly). Remember, he's not that good of a detective. They use him because he's willing to do dirty work and is expendable.

It feels like he's not that good of an actor, frankly.

Isn't that the express purpose of the scene?
