Director Steven Spielberg, actor and playwright Mark Rylance, physicist Professor Stephen Hawking, TV personality Simon Cowell, and The Duchess of Cornwall are among 50 high profile personalities who have put their childhood dreams and aspirations on show around the country – including in London – to mark not only the release of the film The BFG but also the 100th anniversary of Roald Dahl’s birth. Launched last weekend, the ‘BFG Dream Jar Trail’ features a series of up-to-six-foot-tall ‘Dream Jars’, each of which contains a sculpture representing the childhood dreams of a different personality. The free trail – which takes in London sites such as Trafalgar Square, the Tower of London, Leicester Square, Harrods, Emirates Stadium and The Shard – has been created in support of the work of Save the Children and a specialist nursing programme supported by Roald Dahl’s Marvellous Children’s Charity with the jars to be auctioned in collaboration with Paddle8 later this year to raise money for both causes (the auction will be launched on the film’s premiere on 17th July). At least 34 jars have already gone on display with more to be unveiled in coming days. The joint creation of  Save the Children, the Roald Dahl Literary Estate, Entertainment One and VisitLondon.com with support from Unilever, the trail can be seen until 31st August.
