I originally saw this while I was living in Norway. As such, it had Norwegian subtitles across the bottom of the screen. I was, at the time, serving as a missionary for the Church of Jesus Christ of Latter-Day Saints (the Mormons).
The two main players in the early days of the church were Joseph Smith and Brigham Young. Joseph Smith was the founder of the church, and Brigham Young later took the reins after his death, leading the members of the church to modern-day Utah. This movie deals with these early days of the church.
Brigham Young was well portrayed. Everything I've read about the man says this portrayal was spot-on. At first, I thought Joseph Smith had been miscast. I mean, come on: Richard Moll (who plays Joseph Smith) is better known as "Bull" Shannon on "Night Court." In retrospect, it's not that far off. The real Joseph Smith was well over six feet tall, and was generally known for being a very gentle person.
The early persecution of the church, and the subject of polygamy are dealt with head-on, and accurately.
All-told, a decent movie, carried by the strength of the stories and the portrayals. The budget is pretty low, so don't expect too much flash.
