Here's a random sample from our local library. The aspect ratios are from the box, Netflix, or IMDB depending on where I could find them.
Mona Lisa 1986 1.78:1 Letterbox
My Best Friend 1.78:1 Anamorphic
Panic 2000 1.78:1 Anamorphic
Prince of the City 1981 1.78:1 Anamorphic
Sherrybaby 2006 1.78:1 Anamorphic
The Gathering Storm 2003 1.78:1 Anamorphic
Blissfully Yours 2001 1.78:1 Anamorphic
Climates 2006 1.78:1 Anamorphic
Cyclo 1995 1.78:1 Letterbox
The Crime of Padre Amaro 2002 1.78:1 Anamorphic
Matchstick Men 2003 1.78:1 Unknown
The Day of the Locust 144M 1975 1.78:1 Unknown
It seems to me that 1.85:1 aspect ratios are popular with major film producers for comedy and romance, and that ~2.35:1 is popular for adventure and block buster films.
Most of these films are foreign, and as far as I know, none of them were made with a HD video camera.
Edit: Maybe a good place to continue this discussion would be in the "black bar" thread that's linked at the bottom of my post.
