As we reach one hundred years since the end of World War I, The Royal British Legion, along with a number of recognisable personalities, give thanks to The Great War generation and the legacy they left behind. The centenary campaign, created by Leagas Delaney, is the culmination of The British Legion's 'Thank You' movement, and features such prominent TV British figures as Bear Grylls and Mark Strong, alongside revered war veteran Lance Sergeant Johnson Beharry VC and Justine Roberts, the founder of Mumsnet. Running alongside the Poppy Appeal, the campaign aims to not only recognise the sacrifices made by the Armed Forces, but by those men, women and children who remained on the Home Front, and the legacy that flowered out of the hardship. Acknowledging that their wonderful legacy includes not just ground-breaking social change and works of art, throughout the film, the star-studded cast recognise the pioneering innovations in medicine and technology that came out of the war, such as prosthetics and parachutes.CreditsCampaign talentBear Grylls, adventurer and TV presenterMark Strong, actorJohnson Beharry VC, British soldierDr Christian Jessen, doctor and television presenterJustine Roberts CBE, founder of MumsnetTina Hobley, actress and radio presenterRichard Whitehead MBE, gold medal winning paralympian Client: Royal British LegionAdvertising Agency: Leagas DelaneyAgency Creative Director: Tim DelaneyCopywriter: Simon Welch Art Director: Matt WelchPlanning Director: Owen DowlingPlanner: George WhiteBusiness Director: Emily MetcalfeAccount Director: Olly HobsonAgency Producer: Glenn PatonMedia Company: VCCP / PeriscopixProduction Company: Nice Shirt FilmsDirector: Stuart Douglas and TareqEditor: Simon EustacePost-production: Raised by WolvesAudio post-production: 750mphTalent Management: Chloe Franses & Co
