In the 2003 movie *Luther*, Katarina von Bora (future wife of Martin Luther) says that she escaped from her convent with other nuns by hiding in herring barrels. But we see that Luther did not need to take such drastic matters to leave his monastery, and that he worked among the people anyway andseems to have been able to come and go as he pleased.

Is there some aspect of this movie that is artistic license? Why did Katarina von Bora need to escape from her convent in a barrel when Luther did not need to do anything of the sort?
