Okay, I looked at the IMDB's BAFTA pages, and found some information.
Little Brave Heart isn't in the database, so no help there. The only new information is that the film was made in 1954 - but I'd take that with a grain of salt. All of the nominees that aren't in the database seem to be labelled with the year of the award, suggesting that whoever typed this up just bunged in the most likely-sounding year. Quite a few of the foreign-language films came out some time before they won BAFTAS, and Little Brave Heart could easily be one of them.
Love and the Sepplin is listed as "Love and the Seppelin", although this title doesn't turn up anything useful on Google - just more sites covering the BAFTAS. IMDB also says that the film is from Czechoslovakia. At this point I'm pretty certain that the film in question is actually Love and the Zeppelin, AKA Laska A Vzducholod, AKA An Airship and Love. But the question is, can I say so on the article? Over at Wikipedia this'd qualify as original research, which is frowned upon in those parts.
For the Magic Flute, though, I think the mystery's solved. According to IMDB this film is actually The Magic Fluke, a John Hubley short. Show of hands - do we go with IMDB, or the BAFTA database?
One last thing - IMDB says that The Travelling Rune, one of the films I added to the page today, is from Holland. That's all I've got.
