It has been announced that her cameo appearance in the last episode of Dr Who was just a taster of things to come. Catherine Tate is to be taking a more proactive role in this year's Christmas special.

Tate's part was limited to a sneak glimpse of her character-to-come in the Tardis in full wedding dress. She is to play Donna in the special - a runaway bride - and comes on board the time-travelling adventures just as Billie Piper's character, Rose, has disembarked.

The Christmas episode is being filmed this summer and, although, she is stepping in as a void in side-kickedness is created she isn't going to be a permanent fixture. The Dr's full time companion is to be Freema Agyeman.

The episode writer, Russell T Davies, said, "Doctor Who and Catherine Tate is just the most irresistible combination, a genuine treat for Christmas viewing.

"After two years of travelling with Rose, the Tardis is in for a bumpy ride with Donna on board."
 
Could've been a bit more interesting had it been her two-faced granny.
