An entirely gratuitous picture of the Doctor in a Santa hat.
According to the Radio Times, reporting on the preview screening of The Snowmen, "special episodes celebrating the Time Lord's half-century will be...". Special episodes? Plural? A typo - or are we going to get more than one anniversary special? Might Series 8 actually comprise a number of specials rather than a full series - as with Tennant's final year? The other day I mentioned Kasterborous.com's query about Series 8. Is this the answer?
