In the late 1980s Jon Ronson was the keyboard player in the Frank Sidebottom Oh Blimey Big Band. Frank wore a big fake head. Nobody outside his inner circle knew his true identity. This became the subject of feverish speculation during his zenith years. Together, they rode relatively high. Then it all went wrong. Twenty-five years later and Jon has co-written a movie, Frank, inspired by his time in this great and bizarre band. Frank is set for release in 2014, starring Michael Fassbender, Maggie Gyllenhaal, and Domhnall Gleeson and directed by Lenny Abrahamson.
