Concrete Circus -- A new generation of the very best urban sports stars are teaming up with incredible young filmmakers. Together they've produced stunning films that have captured the attention - and the imagination - of tens of millions of viewers. For the very first time, Concrete Circus, directed by Mike Christie (Jump London, Inside Incredible Athletes), brings together five of the worlds best street sport talents and their amazing film-makers. Their recent films have it all: beauty, danger, jaw-dropping action, and - between them - nearly 50 million online views. They are: urban trial-rider global phenomenon Danny McAskill, from Scotland; Spanish skateboarding virtuoso Kilian Martin; British free runner Blue and the extraordinary 19-year-old parkouriste Phil Doyle (who are joined for an impressive cameo by the incredible Canadian parkour/skater Mathieu Ledoux); and, last but not least, UK champion BMX flatlander Keelan Phillips. This feature-length documentary follows each team as they set about making 4 brand new films with their film-makers: the UK s Stu Thomson and Claudiu Voicu, Brett Novak from Los Angeles, and Parisian Kendy Ty. The premiere of the four new films forms the centrepiece of the documentary. Can they better their first spectacular films? Can they jump further, move faster, risk more? How far do they have to go to go further than ever before? Concrete Circus climaxes with an action-packed scene shot in London and directed by Christie, featuring Danny, Kilian, Blue, Phil and Keelan together on screen for the first time. This truly international and inspirational film also features key and eloquent pioneers from each of the sports: Sebastien Foucan (parkour pioneer who starred in Casino Royale), Bob Haro (BMX pioneer who starred in ET), Hans Rey (multiple world champion Trials Rider) and Mike Vallely (street skateboarding legend, The Hangover).
