This Week In Doctor Who Alert.
The 7 day schedule for May 21 through 27 is out!
s.pdf (Note: spoilers for episode and most BBC programming at that
Doctor Who - The Empty Child airs from 6:25 to 7:10PM (note the time)
on BBC One on Saturday 21 May.
This is likely because BBC One has live Eurovision coverage from 8PM
to 11:20PM, and they'll want to get the full Lottery show in by 8. It
is presumably a one time only change in the BBC One broadcast time.
There is no mention of Doctor Who Confidential on BBC Three, though
the TWIDW column expects the start time would move as a result of the
Doctor Who time change. BBC Three is airing additional Eurovision
coverage from 11:20PM to 12:20AM, which will affect the late night
Doctor Who and Confidential repeats there.
