The French hold the playwright Moliere in the high esteem the English-speaking world reserves for Shakespeare.
Like the Bard of Avon, there is mystery about Moliere's life.
In 1644 the authorities threw Moliere, then a struggling actor, into debtors prison.
On his release, he disappeared for six months. On his return, he led his company on a 13-year tour which was to make him famous, and earned him a place at the French Court.
When French film director Laurant Tirard heard this story, it got him thinking. He told Minnesota Public Radio's Euan Kerr it led him to making his new film called "Moliere."
