F for FailEXCLUSIVE: Examples of  tiny self-financed movies getting picked up are rare indeed. Normally, such pics disappear without a trace. But Optimum, the UK distribution arm of Studio Canal, is set to acquire this low-budget horror movie, titled F, and plans to release the shocker this autumn. The film’s pitched as “Assault On Precinct 13 set in a school”.  Producers Paul Blacknell and Ernest Riera raised the sub-£1 million budget themselves through private City investors. Director Johannes Roberts is represented by Independent Talent. Their joint Black Robe production company plans to develop a slate of UK films budgeted between £500,000 and £10 million over the next five years.
