On October 31 the Daily Mail reported the following:

Claire Foy, who - despite being so good in the BBC TV serial Little Dorrit - has moved quickly to ensure she doesn’t get typecast in angelic roles. Claire is playing a sorceress in Season Of The Witch opposite Nicolas Cage and Stephen Campbell Moore. Shooting begins next week in Hungary. The film is set in the 14th century and features tales of witchcraft, religious intolerance and the Black Death. Meanwhile, Eddie Marsan, who plays Mr Pancks the intrepid sleuth in Little Dorrit, is a Scotland Yard detective in Guy Ritchie’s Sherlock Holmes movie. ‘I’m Starse of the Yard,’ he said at the nominations launch for the British Independent Film Awards, in which he was nominated for his performance as a driving instructor in Mike Leigh’s movie Happy-Go-Lucky.

Variety also had an article back in October about the project:

“Hellboy” topliner Ron Perlman has signed on to star opposite Nicolas Cage in the supernatural thriller “Season of the Witch” for Relativity Media and Atlas Entertainment. Dominic Sena is helming from a Bragi Schut screenplay.

“Season of the Witch” tells the story of 14th century knights transporting a girl suspected of being a witch responsible for spreading the Black Plague.

Stephen Campbell Moore, Claire Foy and Robbie Sheehan round out the cast. Shooting will start in early November in Austria and Hungary.
