Multi-talented Mark, 28, from Northern Ireland (above, right), has two masters degrees in law and radio production and admits to being the ‘ultimate Trekkie’. The film and drama graduate used his radio experience to produce bi-monthly podcasts for an east London radio station, debating sci-fi films, geeky places to visit and general ‘nerd news’. Sorry, there was a problem. Despite his magnificent size, Danny, thor costume is actually a gentle giant and loves to play with children and any cats in the neighbourhood – even if the feeling isn’t always mutual.
