And let's hope for her sake, it all nets out better than the short-lived NBC reboot did!

Michelle Ryan, who of course starred as EastEnders' Zoe before attempting to fill Jaime Sommers' shoes stateside, has been tapped to guest-star on a Doctor Who special premiering this spring on BBC One.

In the Easter special, which is (perhaps ironically?) titled "Planet of the Dead," Ryan will play Lady Christina de Souza, a mystery woman who joins the Doctor on an unexpectedly dangerous bus tour.

"I'm a huge fan of Doctor Who and very excited to be joining David Tennant and the Doctor Who team," Ryan says in a statement. "It is such a fantastic show."

"Planet of the Dead" is the first of four Doctor Who specials scheduled to air in 2009. Guest-starring alongside Ryan is Lee Evans, who is described by the BBC press release as "one of Britain's best loved and biggest comedy stars." And really, who am I to argue?
