Colin Firth stars as a veteran secret agent who leads a young protÃ©gÃ© (Taron Egerton) into the shadowy business. Samuel L. Jackson and Michael Caine also star. There’s no word on what Cookson’s specific role will be but she will be a female lead.
Vaughn will produce with Tarquin Park.
Cookson is an up-and-comer who has previously appeared in the mini-series “Moonfleet” and will next be seen in the TV movie “Unknown Heart.”
She is repped by Curtis Brown Group.
