I Miss Sonia Henie (1971)

er, i mean, besides the imdb entry. does it actually exist?

Yes, apparently it does indeed exist. My evolving web page on this most elusive of unreleased (but extant!) films is at http://home.earthlink.net/~busterktn/tintowk4.html

There's still more information, which I haven't yet gotten permission to quote. But I have spoken with both Tinto Brass (whom I interviewed in April) and Buck Henry (whom I happened to bump into in a Hollywood videoshop a few months ago), and they both told me a little about the film. Very little.

Ciao!
