The scene in 2006’s “Amazing Grace” where William Wilberforce (Played by Ioan Gruffudd) sings “Amazing Grace” at the card house was actually directly sung from actor Gruffudd at that moment. In the last several takes, a playback was used, but it is Ioan singing and this was because director Michael Apted had no idea whether or not Gruffudd could actually sing. Little did Apted know, Gruffudd is an accomplished soloist and choir singer. With a little practice, Gruffudd performed for the first time on set while the cameras were rolling, all much to the surprise of the cast, crew and director. Was it God’s will?
