Six months after back surgery at DISC, street trials rider Danny MacAskill is back in Scotland and focused on preparations for his new riding film. MacAskill, who also spent time rehabbing at the Soft Tissue Center, is now training, practicing and attempting new tricks for the film project in episode four of his documentary, “Imaginate.” The secret project, which will be filmed in 60 days, has been in the works for over a year but was delayed while he underwent surgery and recovered. Prior to the start of filming, his ideas come to life as props, including an army tank, are brought in for MacAskill by his team.
