In striking contrast to most actors, directors are almost always interesting, none more so than the rebel Robert Altman who defied the conventions of Hollywood cinema to make his own movies, which exploded myths about American culture.

In Ron Mann's affectionate documentary tribute we hear the maverick auteur dismiss the idea that he was intentionally taking a swipe at the system - "I reflect what I see and feel" - but films such as M.A.S.H and Nashville speak for themselves and The Player is the ultimate dig at the Hollywood studio system that never understood him.

Regardless, Altman gained a level of respect that was so high, like Hitchcock and Welles before him, an adjective was coined from his name and everyone in the film is asked to give their interpretation of what "Altmanesque" means to them.

As the director himself observed: "I make gloves and Hollywood sells shoes", which is why Altmanesque for me means unmissable cinema.
