In a pre-Toronto Film Festival move, British actress Sophie Cookson has come on board opposite Adrien Brody in historical action-adventure “Emperor”, Variety reported.

Other cast members in “Emperor,” directed by Lee Tamahori, include Paz Vega (“Talk to Her”), Gotz Otto (“Cloud Atlas”) Bill Skarsgard (“Anna Karenina”), Thomas Kretschmann (“Valkyrie”), Oliver Platt and Rutger Hauer.

Eddie Marsan is in talks for a role and Belgian actors Sam Louwyck, Michael Pas and Lize Feryn (“The White Queen”) complete the cast.

The project was announced at Cannes with Brody and Tamahori attached. Shooting starts Sept. 1 in Prague and Ghent.

Producers are Courson NV topper Paul Breuls, Michael John Fedun and Catherine Vandeleene. Guy Tannahill is exec producing and Richard McCallum serves as co-producer.

The script is written by Michael Thomas III (“The Devil’s Double”) and Jeffrey Hatcher (“The Duchess”). Cookson plays a feisty and daring 21-year-old who infiltrates the court of Holy Roman Emperor Charles V (Brody) to avenge the death of her father at a time when the emperor is struggling to hold together a fragmented empire in a world of wealth, debauchery, intrigue and treason.

Cookson will soon be seen as the female lead opposite Samuel L. Jackson, Michael Caine and Colin Firth in Matthew Vaughn’s “Kingsman: The Secret Service.”
