Wonderful music by Bernard Herrmann
Herrmann is one of my favorite movie composers, and I've often noticed similar melodies and motifs in a number of his scores.
I had only seen Hangover Square once before, and don't recall noticing it then, but on my last viewing a few days ago, it stuck me that there's a very sweet, sad melody played near the beginning of Bone's concerto that is strikingly similar to the sad, impassioned love theme from Hitchcock's Vertigo some fourteen years later. You'll know it when you hear it.
It really struck me as a powerful indicator of the sadness and hopelessness of Cregar's character, as a sensitive, gentle man, in love with an undeserving b*tch, while seeming to be unaware of the true love felt for him by his devoted female friend. The combination of the brilliant cinematography and lighting, Cregar's performance, and Herrmann's music, in the scene where Bone is writing that part of his concerto, and looking like such a lost soul, practically brought tears to my eyes.
I have seldom been so affected by a movie, especially one that's " only an old horror movie". Cregar is absolutely heartbreaking, and Herrmann's music adds an unforgettable touch to the character's personality.
And when he crossed the bridge, the phantoms came to meet him
