This is one of my favorite stories from childhood and this Disney cartoon did a wonderful job of capturing the spirit of the classic Muro Leaf story. The 1939 Oscars were a particularly good year, with Disney receiving 4 of 5 nominations in the category of Best Cartoon and receiving the award for FERDINAND--beating out such Disney classics as THE BRAVE LITTLE TAILOR and GOOD SCOUTS.
The film is about a gentle bull in Spain who has no interest in fighting. Instead, he'd rather just sit and smell the flowers all day. However, when men come looking for fierce bulls for the bullfighting ring, they think Ferdinand is the meanest bull because he was just stung by a bee. What happens next you'll need to see for yourself.
There is a lot to like about this cartoon. The artwork, though not exactly in the style of the children's book, is pretty close and is among the better animated shorts Disney did in the era. If you compare the artwork, music and quality to fare from Fleischer, Warner Brothers and MGM at the same time, it is light-years ahead. The best cartoons at that time were clearly Disney--with MGM and Warner Brothers still making saccharine-sweet cartoons with second-rate animation until the 1940s (when these two studios became the best maker of cartoon shorts). This film just screams "quality" throughout and deserved the Oscar.
By the way, get a load of the Cork Tree! Ha!
