Johann Sebastian Bach had a total of 20 siblings, but many of them did not survive to adulthood. Specifically, six of his brothers and sisters died in infancy or childhood. This high mortality rate was common during that period due to various health issues and lack of medical care.
Johann Sebastian Bach did not live in a church. However when he was about 15 years old, he and his friend, Georg, made a long journey to Luneburg. Along the way, they stayed at many monasteries, which are residences of usually religious people.
This is a somewhat anachronistic question, as movies did not exist in the lifetime of Johann Sebastian Bach (1685-1750). However, I am sure that in the twentieth century, his music was arranged or used for many movies by twentieth century composers.
Johann Sebastian Bach had four sons: Carl Philipp Emanuel, Johann Christian, Wilhelm Friedmann, and Johann Christoph Friedrich. The first two became prestigious composers in their times, particularly C. P. E. Bach (as he is usually identified from his father J.S. Bach).
