Film Festival this month, follows Brit artist Andrew Logan and his outrageous Alternative Miss World Show, an anarchic costume pageant, which he has hosted since 1972. Pic is the fifth feature from Film London’s low-budget Microwave scheme to secure U.K. distribution. BBC Films and the Film Agency for Wales also backed the project with support from Skillset. Jes Benstock directs the docu while Dorigen Hammond produces. Docu features Brian Eno, Zandra Rhodes, Richard O’Brien and Grayson Perry, and was filmed over five years charting the mounting of the 2009 show.
