I was just going on what I've read, it's possibly wrong
I did look up the official definitions of the categories. 'Best film' is actually 'THE MICHAEL BALCON AWARD for Outstanding British Contribution to Cinema' which The Queen won.
Quote:
This award is in the gift of the Academy's Film Committee. Its primary purpose is to honour the talents of individuals from the industry whose achievements are not usually recognised in other award categories.
‘Best British film’ goes by the full title, ‘THE ALEXANDER KORDA AWARD for the Outstanding British Film of the Year’ which the THE LAST KING OF SCOTLAND won.
Quote:
. Director(s), Writer(s) and a maximum of three Producers are eligible.
. The Academy adheres to the definition laid down by the Department for Culture, Media and Sport when determining whether a film is British.
. The nominees and winner of this award are decided by a combination of membership vote, Film Committee discussion and jury.
