Emilia Fox has joked that she is jealous that her co-star Robbie Kay has landed a role in Pirates of the Caribbean 4.
Fox stars alongside teenager Kay in her latest movie Ways To Live Forever, in which they play mother and son.
Speaking to the Press Association the actress said: "Before Christmas I did a film called Ways To Live Forever about a little boy who had cancer with a brilliant actor called Robbie Kay, who's just phoned me to tell me he's got a job in Pirates Of The Caribbean.
"I told him I didn't want to be replaced by Penelope Cruz in his life and that I was slightly envious that he was going to Hawaii for 10 weeks - and does he need a chaperone?"
Ways To Live Forever follows a family as their son, played by Kay, is diagnosed with leukaemia. And Fox reveals that it was an emotional project to work on.
"The very thought of having a child who gets a terminal illness like that, I don't know how you deal with it.
"I think there are incredible people and incredible families who find their way of dealing with it. So we all got very close on the film and remain friends."
