The Guardian awarded the film three out of five stars and said "producer-director Kari Skogland has put together an effective, if cinematically unambitious, enterprise." Martin McGartland disowned the film as was reported in
The Sunday Times on 29 March 2009. He told the publication that "they are saying it was based on a true story, but what is the definition of 'based on a true story'? Is it 50% true, 70% true, 10%?" The
Sunday Times further reported that McGartland contended "that the movie is fundamentally a lie that misrepresents his career and his motivation. He believes that if
Kari Skogland, the director, had stuck closer to the account he gave in his book and in a
BBC documentary, then she would have had a better film." ==Accolades==
