Page "Tooth and Claw (Doctor Who)" Paragraph 12

Pauline Collins appeared previously in the series as Samantha Briggs in the Second Doctor serial The Faceless Ones ( 1967 ).

This makes her the third actor from the classic series to appear in the new series, following William Thomas ( Remembrance of the Daleks and " Boom Town ") and Nisha Nayar ( Paradise Towers and " Bad Wolf "/" The Parting of the Ways ").

Collins had been offered a role as a companion in 1967, but had turned this down.

According to the accompanying episode commentary, actor Tom Smith, who played the Host, studied at drama school with David Tennant.
