I saw a movie a few years ago that I have been trying to remember the title of since. The movie was in black and white, but from my memory it was from the 70s-90s. From what I remember, it was about a man who is being sent all over a city due to strange phone calls he receives in the car. Towards the middle-to-end of the movie, he is goes into a large, VERY modernist in style house, but it has been recently vacated (if memory serves correctly, it had been the home of his uncle). I distinctly remember him picking up a watch and looking at it in this house. While a small detail, I feel like this was a turning point in the plot. Sure would appreciate any help!
