According to BBC journalist Lizo Mzimba on Twitter, the first television trailer for the forthcoming Doctor Who special, "Planet of the Dead", will air on BBC One on Wednesday at 9 pm, just prior to "The Apprentice".
Trailers for the special have already appeared before live audiences at a Wales rugby match and at the "Story of Doctor Who" event at the Celtic Media Festival. However, Mzimba tweets, "You didn't hear this from me. But trailer is a brand new one. It's not the one shown at the Wales V Ireland Rugby or anywhere else."
