Dom Joly and The Black Island Friday 19th March, 7.30pm on Channel 4

The ever-enthusiastic Dom Joly dons the costume of his hero, complete with shorts, plus fours, a white shirt and blue jersey, and even dyes his hair ginger. He goes to Brussels and visits the studio where Herge drew the character. Ever faithful to his quest, Dom goes in search of a Snowy the Dog and visits a seaman's bar in an attempt to find a Captain Haddock look-alike.Dom Joly and The Black Island Friday 19th March at 7.30pm on Channel 4
