There are many instances when actual quotes are used by the characters. This includes Friar Tetzel's (Alfred Molina's) "Coin in the coffer rings a soul from Purgatory springs", as well as Luther's "Here I Stand" speech.
The film was co-produced by Thrivent Financial, an American company affiliated with the Lutheran church, primarily The Evangelical Lutheran Church in America and The Lutheran Church - Missouri Synod. It's a members-only company, serving congregants of Lutheran churches, operating much like a credit union or mutual insurance company.
Thrivent is the only not-for-profit in the Fortune 500.
The film has 61 credited actors and five credited actresses.
