Filming has commenced for the 2013 Doctor Who Christmas Special  and on 10 September the crew was spotted in Cardiff. Matt Smith, who is currently bearing a skin-head type hairdo following his filming of How to Catch a Monster in Detroit earlier this year, donned a floppy hair wig for the occasion. The Christmas Special will be Smith’s last appearance in Doctor Who and will see him regenerate into the Twelfth Doctor, Peter Capaldi.
