I came across this interview in the forum (http://www.projecta.net/nolan2.htm) and i wonder what movie the 2nd Project is he talks about: We are working on two things at the moment. One is American and the other even though it is for an American company it's an English project and will be set in London. I don't know which of them is going to happen first, but it's kind of good I'm doing them both.
I guess the American Project is Memento?! Is there any information about this 2nd. Project? I think he gave it a pass after he was approached to make insomnia.

I only heard about this 2 movies he planned to do after insomnia, "the keys to the street" and a Howard Hughes biographical film.

Your assumption is correct, that would be The Keys to the Street (English crime novel) for Fox Searchlight (American company). He also looked at adapting the British television series The Prisoner and the futuristic comic The Exec.
