John Hannah

On 24 December 1997, Hannah and Scottish Films producer Murray Ferguson established a production company called Clerkenwell Films. Clerkenwell's first big production was the Rebus series, including Black And Blue and The Hanging Garden. However, Rebus was later taken in-house by STV Productions, and Hannah was replaced in the leading role in the series by Ken Stott.

Hannah married actress Joanna Roth on 20 January 1996. The pair met several years before during a studio production of Shakespeare's Measure for Measure. In many of his interviews he mentions stories from their relationship, such as the visit to London's 'Sri Siam' restaurant where he proposed to her in writing on the tablecloth. They live in Richmond, London with their two children.

After graduation, Hannah had parts in theatre productions, films and television, which included leading roles. He broke into the "big-time" with his appearance as Matthew in Four Weddings and a Funeral (1994). Since this breakthrough role, he has played a psychopathic killer alongside Helen Baxendale in Truth or Dare and a mystery-solving pathologist in McCallum. He was a karaoke-mad dead-beat dad in The James Gang, a drunken, thieving comic-relief character in The Mummy (1999) and The Mummy Returns (2001) and a Monty Python-quoting romantic comedy love interest in Sliding Doors (1998). Hannah also starred in the axed U.S. series MDs (2002), as well as making guest appearances in Alias (2001), Carnivàle (2002) and Frasier (2003). In 2006 he starred in the drama series New Street Law. In 2007–08, he played a starring role in the ITV crime drama Cold Blood.
