Ah,
Bridge too Far. Some facts. The DC-3s were a mix from within Europe - I have an article (somewhere - not to hand, I'm afraid) in an Aircraft Illustrated in the 1970s written by the chap that arranged the jump scenes. Most of the ground troops were Dutch, and IIRC the airborne were a mix of Dutch and British - but I'll have to check. Wonder where it is?
There was a thread on the Flypast Forum about one of the Daks, trying to establish if it was in 'both' Market Garden (real & film) opps.
Edit - Thread here. Why they didn't post the full list of aircraft...

If you are interested in the film and original story, there's an excellent magazine 'After the Battle' special on a Bridge too Far, with lots of behind the scenes stuff. Also a book on the making of the film with interviews with the original warriors and the actors, as well as the Cornelius Ryan book which the film was based on.
Bf109K4 - Great post. Couple of footnotes - The Spanish stuff was 'The Battle of Britain' film, 1967, while Bridge (the para stuff) was 1970s. The Czech film (highly recommended - go see / get) was 'Dark Blue World' which used out-takes from Battle of Britain. Much of the Battle of Britain film stuff is well covered by various books, including two modern ones by Robert Rudhall, and a contemporary (with the film) one 'Making of... IIRC.
More when I've done some checking.
Nothing on Band of Brothers, I'm afraid.
