Rosario is Ryan's new leading lady
The film is being directed by Canadian Atom Egoyan, who co-wrote the script, which will see Ryan play the father of an abducted child.
Rosario has joined the cast, according to The Hollywood Reporter, but her role in the film is unknown and details of the plot are being kept strictly under wraps.
Scott Speedman and Gangster Squad's Mireille Enos have also apparently been signed up as part of the ensemble cast.
Filming is due to being in Ontario later this month.
