A press statement said that the programme would be broadcast in 3D, using some of the BBC's high-definition capacity, as part of the blockbuster celebrations to mark the show turning 50. Showrunner Steven Moffat said:
It's about time. Technology has finally caught up with Doctor Who and your television is now bigger on the inside. A whole new dimension of adventure for the Doctor to explore.The use of the advance in broadcasting technology for the programme was revealed during an event for writers, actors, industry, and press at which BBC drama controller Ben Stephenson set out his vision for BBC Drama, announcing new commissions, recommissions, and looking forward to new horizons:
Drama and the BBC are inseparable – it is written through the BBC like a stick of rock. No other broadcaster in the world has drama so firmly in its DNA . . . I want to make BBC drama a cultural institution – a touchstone for quality and modernity with all the excitement and glamour of a curtain going up . . . I want to make the BBC the hallmark of quality drama.
This isn't the first time the show has entered the 3D waters. Back in 1993 Doctor Who's 30th anniversary was marked with Dimensions In Time, broadcast in 3D for that year's Children in Need. And in 2010 the Eleventh Doctor's era was heralded by a 3D trailer shown in cinemas, as can be seen below (NB: 3D anaglyph red/cyan glasses are needed for the full benefit):
Also in 2010 a poll was undertaken by entertainment manufacturer Panasonic that revealed Doctor Who was the show that viewers would most like to see in 3D, with other favourites being Wallace and Gromit and Top Gear.
