Andrew added the "Hayden" part to his surname because there was already another actor called "Andrew Smith".
(About the most embarrassing thing he's ever done on television)
Andrew: I once had to dress up in this massive chicken outfit. I fell over and it was so heavy that I couldn't get up.
Andrew is 1.73 cm (5 ft 8 in) tall.
Andrew has appeared in several pantomimes and played Peter Pan in Halifax and Dandini in Cinderella in Maidstone.
Andrew became a 'heart-throb' while playing Ben in the CBBC drama Byker Grove. He was so popular with viewers that CBBC soon snapped him up onto its presenting team.
(About acting in Doctor Who)
Andrew: The only acting I'd done was children's drama so it's great I've finally got a foot in the door of grown-up TV. I was a bit nervous because Doctor Who is such a huge success, the best thing on TV as far as I'm concerned.
