During an interview with Steve Ryder Prost said that the thing that really gutted him about the film was that when he asked why that "A Special hello to my friend Alain" radio transmission from Senna during a car-to-TV channel stream (incidentally why have they stopped doing that?... They haven't done it since Hill's Silverstone quali in 1994...) had been left out of the film , he was told by the producers that that message had been a montage by french TV, had been doctored, wasn't real etc...
Kind of says it all really...
