Colman will step into the role of Elizabeth II for the series' third and fourth seasons as the action of the show moves closer toward the present day .
Foy, who will be seen playing the role of Queen Elizabeth in the upcoming second season of the series, has revealed that she is "thrilled" to pass the crown to Colman .
While talking to Vanity Fair, at this year's B .A .F .T .A . Britannia Awards, Foy said, "I've known for a long time . I found out many, many months ago, and I was just like, yes, just do it! Whatever happens, don't let her get away . Make her do it ."
Adding, "It was to the point where I actually spoke to her on the phone and told her, you have to do it . You have to do it! She's the most extraordinary actress and person in every single way . I love her, so I'm thrilled . I have always loved her . I can't wait to see her in it ."
Asked if she had any advice for Colman, she replied, "There's no shortcut in playing the Queen . It's for her to discover, and she'll probably find out lots of things that I never found out . She'll play the Queen at a very different time to me . It's a rolling thing, and it's ever-changing and ever-revolving . I think the most important thing for her is to just do it, and not think about anyone else who has ever done it before . It's a challenging role, but she knows what she's doing . She'll completely reinvent it and make it her own ."
