I am trying to find a foreign movie I viewed once. I believe it had subtitles. The underlying story involves a violent criminal who plans to steal money from an associate who is also crooked. He befriends a mild mannered female clerk to help him along the way. She is able to learn details to help the gangster by sitting on top of the rooftop with binoculars and lip reading the conversations of others. In the end, this unlikely duo help each other. He beats her coworker to a pulp when he tries to steal credit for her ideas and impress their boss.

Possibly this:

Bravo. You were both quick and efficient. Thank you so much for helping me locate this film. Now off to the video store. Oh wait. It's 2:00 AM here. Glad to know there are other insomniacs out there.

Ha! Glad it's what you were looking for, I think it was 10-11ish last night when I posted that... welcome to the site! :)
