Can anyone tell me what the name of this movie is?

My step-dad is looking for it. The movie is about King Arthur, it had a blond actor in it, but not a big name. The only thing he can remember about it is a scene where a group of people are being chased across the ice, and once they get across someone hits the ice and cracks it. The people chasing them then fall into the water. I know it isn't much to go on, but if anyone knows that would be great! Thanks!
