"Whilst talking to Jo Whiley on BBC Radio 2, Russell was asked if she had ever been in Doctor Who, to which Davies replied to: "She?s been offered and madam was too busy, but not this time?.
He went on to add how she was offered a role previously but Russell privately asked her to decline it because ?there?s a better part coming?."
Personally, I'd rather they concentrated on getting the script and stories correct instead on getting Hollywood-types to appear in the show!
