Liam Neeson - No
While filming a movie in Istanbul, Liam Neeson was quoted as “thinking about becoming a muslim” in response to the call to prayer. He said, “The Call to Prayer happens five times a day and for the first week it drives you crazy, and then it just gets into your spirit and it’s the most beautiful, beautiful thing… There are 4,000 mosques in the city. Some are just stunning and it really makes me think about becoming a Muslim.”
Neeson did not actually convert, however. He does look awesome in a beard though!
