Amazing Grace and William Wilberforce

I look forward to seeing Amazing Grace: The Movie, a movie about William Wilberforce, either in the local theater or on DVD (I've popped it into my Netflix queue!) The review of Amazing Grace in the NY Times was lukewarm. Wilberforce's life and example have intrigued me since I first read Every Arrow Needs a Bow: William Wilberforce almost 10 years ago.
