CANNES — Mozart drama “Interlude in Prague,” which stars “War & Peace” thesp Aneurin Barnard, James Purefoy and “Les Miserables” actress Samantha Barks, has started shooting in the Czech capital.

The six-week shoot will take place in several Czech locations, including Libochovice Castle, the Nostitz Theater, Chateau Jemniste and the town of Ploskovice.

The cast also includes rising star Morfydd Clark, who plays Zuzanna Luptac, an 18-year-old soprano who has a passionate affair with Mozart (Barnard), but is forced to marry another man. Clark’s credits include Whit Stillman’s “Love & Friendship.”

The film is directed by John Stephenson from a screenplay by Brian Ashby and Helen Clare Cromarty. Productive International’s Huw Penallt Jones and Hannah Leader are producing.

The story takes place in Prague in 1787 over a few turbulent months in the life of Wolfgang Amadeus Mozart, which influences the creation of the opera “Don Giovanni.” It is a “Shakespeare in Love”-style drama with a tragic ending reminiscent of “Dangerous Liaisons.”

Mozart is brought to the city by Baron Saloka, a self-obsessed aristocrat, apparently above the law, who lives a privileged life. Upon his arrival, Mozart is happy to have found the one place on earth where he feels his talent is appreciated and sets about creating a new opera at the Nostitz Theatre. However, Mozart’s presence in Prague unleashes a series of dramatic and tragic events. Luptak is betrothed to Saloka but falls in love with Mozart, and they have a passionate affair. Saloka, a psychopath, sexual predator and serial rapist, develops an overwhelming hatred that results in callous brutality and murder.
