Corrected entry: At 1:23:19 in the movie, Wilberforce is getting married and his bride has chosen his favorite hymn, you guessed it, "Amazing Grace," to be sung at his wedding. Watch the bride at the end of the song. The words are "was blind but now I see." The bride sings, "was blind but now I'm free." You would have thought the actress would know the words of the song the entire movie is based on.
Corrected entry: There is a scene where Wilberforce and Barbara are walking in the garden, when he is taking his rest cure. He asks her for her opinion on the war with France, and she replies that Britain should 'settle with Napoleon'. This scene is set in 1797, and Napoleon did not come to power until 1799.
