“Set within the musical hub of bustling Vienna at the end of the 18th century, twenty-five-year-old Amadeus arrives in the city no longer a child and determined to carve his own path,” reads the synopsis. “Recently unemployed and without the management of his father, Amadeus finds an unlikely ally in a young singer who will become his wife, fiery Constanze Weber Mozart. Her connections help bring him into the orbit of the Italian opera powerhouse and court composer Antonio Salieri, setting the three of them on a collision course that will ultimately define their lives and their legacies for years to come.”

Gabrielle Creevy plays Mozart’s wife Constanze Weber.

The series is reimagined from Peter Shaffer’s award-winning stage play and will see “Giri/Haji” writer Joe Barton reunite with Sharpe and lead director Julian Farino.
