List of Casualty specials
"Casualty" has produced 19 special episodes, including the first webisode commissioned for a BBC continuing drama. Belinda Campbell, who executively produced the drama between 2007 and 2011, thought that webisodes would be a "new [way] to add value for our loyal fans", something which the team constantly look to do. "Casualty" filmed a sketch for charity telethon "Children in Need" in 2009, featuring charity mascot Pudsey Bear. In 2010, cast members on the show filmed a tribute to BBC soap opera "EastEnders" and "Blue Peter" presenter Joel Defries presented a segment of the show from the "Casualty" set. To celebrate "Casualty" thirtieth anniversary, original cast members Derek Thompson and Cathy Shipton filmed a special episode, "Back to Ours", showing moments from their careers on the show.
