The Emperor and the Golem

It is one of the best known films of Jan Werich, who's performing a dual role of Emperor Rudolf and baker Matěj.

The movie is still quite popular in Czech society, especially due to catchy songs (albeit with some leftist/communist flavour) and the impressive portrait of the Golem, a mythical anthropomorphic robot-like creature allegedly once made from clay by a local rabbi.

Aging and eccentric Emperor Rudolf II, who is obsessed with finding the Golem, refuses to hear out ambassadors and falls into destructive fits.

Rudolf wants alchemist Scotta to make him an elixir of youth and pressures him into performing a magic ritual at night.

When the corrupt head of the bakery leaves the building, Matěj distributes the emperor's bread rolls to the poor and is imprisoned in the dungeons for this deed.

Kelley reveals his homunculus Sirael, whom the Emperor wishes to teach everything of our world, including love.

Kateřina and Matěj communicate through vents between Kelley's room and the dungeons and fall in love through conversation, although they cannot see each other.

Alchemist Scotta concocts an elixir of youth for Rudolf (actually a mix of strong alcoholic drinks and morphium).

Elated by his supposed new vigor, Rudolf and his old loyal servant ride alone in a carriage to the countryside to remind themselves of the sins of their misspent youth.

The emperor's mistress Countess Strada also believes the rejuvenation worked and drinks up the remnants of the concoction.

Matěj as the emperor dismisses Rudolf's astrologer, minimises the extravagant expenses and deals with all the waiting ambassadors.
