Actress Maisie Williams has teamed up with Ric O'Barry's Dolphin Project, a charity aimed at ending the captivity and slaughter of dolphins, to urge people not to attend marine shows.

The Game of Thrones star, who acts as the charity's global ambassador, says it's the best way to stop the capture and killing of dolphins in Taiji, Japan. Williams is the latest celebrity to join the cause to save the dolphins - other campaigners include Brian May, Sting and Daryl Hannah - and commented 'It was something that just struck a chord in my heart. And I'm a firm believer that, if there is something that you really want to stand up and fight for, then you should. And with everyone doing their own little bit for what they believe in, hopefully together we can make the world a better place'.
