The multi-talented Mark Gatiss, who plays Lazarus, has been a fan of Doctor Who all his life. He wrote The Unquiet Dead and The Idiot's Lantern, as well as a number of other Doctor Who books and audio adventures. He even appeared as the Doctor himself, in a sketch for BBC2's Doctor Who Night (broadcast 13th September 1999).
To date, only two other people have both acted in and written for the series (cameo roles excluded): Glyn Jones, who wrote The Space Museum and appeared in The Sontaran Experiment and Victor Pemberton, who wrote Fury From the Deep and appeared in The Moonbase.
According to The Bible (John 11:41-44), Lazarus died and then came back to life after four days when Jesus rolled away the stone from his tomb.
In this episode, we learn that Mr Saxon's first name is Harold and that he has an degree of antipathy towards the Doctor. Quite why, we don't know. Yet.
We've only seen the Mums of two of the Doctor's companions - Rose and Martha. Both Mums have slapped him.

Wells Cathedral in Somerset doubled for the interior of Southwark Cathedral. It's the seat of the Bishop of Bath and Wells.

The Doctor loves nibbles. In The Sea Devils, he demolished an entire plate of sandwiches in seconds.
