Also saw About A Boy this weekend. I really loved it! It was so sweet without being sappy and funny, too.
There were a lot of great knitted items in the film, including the cutest hat, which Toni Collette's character wore. I have tried to find a pic of it, and other additional info, but so far haven't found anything. Look here to see one sample. Toni's hat was similar but it had little pointy ears, sorta like this.
