Well I finally got round to seeing it, and what a good film it is.
I have to agree with Fax about every circuit looking remarkably like Brands, and yes the race scenes were a bit torturous. Overall though I thought it was a bloody good film, and given it's supposed to be entertainment and not a documentary I can live with these small things.
I thought the whole story worked well and the main players did their real life copunterparts justice - especially, as Fax has already mentioned, Bruhl as Niki.
Loved the scene in the hangar at the end.
Glad I finally got to see it - and I had the cinema to myself.
