I don't believe it! A rumour I heard has actually turned out to be true! Yes, Broadcast have confirmed that there exists a 40-second 3D trailer to promote the fifth series of Doctor Who (apparently due in April now, btw), created by Red Bee Media with special-effects by The Mill. The trailer will essentially be the same as the 2D one that premieres this Saturday on BBC1, but converted for 3D in post-production. The 3D promo, entitled "Meet A Monster", will be shown in selected 3D cinemas and promotional screenings across the UK in March.
