Here are links to some trailers.
The Adventists documentary film - Bing video - The SDA live about 10 years longer than people in general of the USA, due to their emphasis on healthy living. That is something I appreciate about them.
There are some similarities between the SDA and WT/JWs. See the following videos.
The Great Disappointment - Bing video - The video mentions Christ will come to his sanctuary; the WT teaches Christ came to the temple in 1918 (or so).
October 22, 1844 - We Know the Date. Film “Tell the World” - Bing video (this video says that a man (an actor portraying Miller?) later realized there was no year 0 and thus his calculation of the year was off; the WT such have learned of that long before the year 1900 AD regarding the 1914 AD date and 606 BC versus the 607 BC).
Ellen Harmon - The Early Years. Film “Tell the World” - Bing video - In video Ellen Harmon (the person portraying her) is troubled by the teaching (by some ministers who endorse Miller's teachings of the Advent of Christ) of the heavenly Father delighting in eternal torment. As we know, Russell was also troubled by that doctrine. In this video the minister tells Ellen and her family that they must stop spreading their teaches or leave the congregation. Ellen's dad they will not stop and if they must leave the congregation then so be it. After they walk out of the church building the head minister says that they (the ministers of the congregation) will announce the "removal from fellowship" of Ellen's family on "next Sunday".
"Ellen White" Visits the Grants Pass SDA Church, pt1 - Bing video is not a movie (unlike the three above) and it is about 30 minutes long. This video has the someone apparently acting the role of Ellen G. White, but this is done in a "modern times" in a "modern" church instead of before the year 1915. The person at the church is giving a speech. She is introduced as being an early pioneer of the church. The JWs also have those who are called pioneers, but Ellen really was a pioneer. I don't which year this video was produced. She is wearing a head covering.
