At this point, it's safe to say we're stumped.

Sorry, I completely forgot that this was still unsolved. Thanks for reminding me. This should allow me to pass the torch:

Could it be Missing, made by my boy Costa-Gavras?

That it is!

Well I have no choice but to respond with...

I'll take the torch right back, because that is of course the great Jean-Louis Trintignant in Costa-Gavras' masterful Z.

And now for something a little different:

Eyes without a face?

Good guess, but this one came out around 7 years later and it's in English.

That's right! Blondie, you're lithe and fierce as a tiger

Frankenstein Created Woman?

Nope.

Hints:

The film's lead actor is probably best known for a string of romantic comedies with Doris Day.

The film's director was responsible for one of most highly-regarded thrillers of the 1960s.

Correct!

Great fucking film. Although watching it with my 12 year old sister was a mistake on many levels

No guesses? This is a great classic, and this scene, which comes about at the halfway point, is one big reason why.

I'll guess Brief Encounter just to keep things moving. The still is all about fidelity though whereas Brief Encounter is opposites.

Quite a bit older. This is from the first American film by a European director.

From earlier in the same film. Same actor, different actress.

I'm fairly certain that's Murnau's Sunrise. If that's correct, someone feel free to take my turn.
