Remake of 2001? I liked both films and i do see some DNA, but on the whole, i feel like both fiilms tried to make completely different things, not to mention the different structure.
I'm hoping Nolan's taking some time with his next script, as his strongest films are usualy the ones he spends the most time scripting. Inception comes to mind, while with The Dark Knight Rises he rushed production a bit more and the film ended up being more problematic.
While i wouldn't mind Nolan doing something smaller, i would like to see him make more "blockbusters", as he has the resources to do whatever he wants right now and too many studios are only releasing sequels and spin-offs.
