The new face of David Tennant: p26

Who on Who? 5.00 pm Radio 2
Did you know that the BBC had plans (quickly vetoed by Russell T Davies himself) to film a Harry Potter-esque spin-off that charted the Doctor's youthful exploits at the Time Lord Academy? Or that RTD was once approached to take part in Dancing on Ice? Well, there are plenty more entertaining titbits like this on offer as the Tardis's departing tenant, sorry Tennant, chats to the man who rebooted Saturday-night TV back in 2005 with his fresh take on a certain sci-fi favourite. Listen out also for the excerpts from Murray Gold's Who soundtrack - sounds ever-so stirring on radio. (David Brown)
