The Mill at Sanssouci (German: Die Mühle von Sanssouci) is a 1926 German silent historical film directed by Siegfried Philippi and Frederic Zelnik and starring Otto Gebühr, Lissi Lind and Jakob Tiedtke.

But the mill of the miller Casper, once the noblest and most expensive construction in the world rattles so loudly, that his majesty feels very disturbed during the time of rest.

He issues an edict which should silence the miller and his mill from functioning during the time of peace, but Casper is beyond stubborn.

Soon the dispute escalates, and Casper decides to even obtain a court ruling in this matter (of which Frederick knows that he can only lose before Justice in view of the equality requirement he had established).

Under various pretenses, His Majesty can promote the marriage of two couples, including two of his soldiers (Lieutenant von Bärenfels and Corporal Jobst) by following in the footsteps of French writer Voltaire, and eventually move things forward in his own amorous affair – his relationship with the dancer Barberina.
