Oh yeah, Costello has obviously immersed himself in music since forever.

I'll check out those movies. I also saw House recently. I was inspired to watch Japanese horror by that bit of it in Cabin in the Woods. House was odd to watch because I knew that foreign movies can be different from Western movies (for instance Bollywood movies will have a song featuring a woman who does nothing else in the movie) so as I was watching I kept thinking things (such as the songs or suddenly having a moment of slapstick) were characteristic of Japanese movies in general! ;-) I didn't realize otherwise until I was watching the special features.
