Williams

Williams ... is charismatic and charming. Morgan Matthews's absorbing and moving documentary also reveals him as maddeningly self-centred, obsessed with motor-racing to the exclusion of all else - but brilliant nonetheless.

The domestic saga is of general interest, but the film is still chiefly for a car-loving audience.

Racing fans are sure to enjoy a history that takes in Patrick Head's innovative car designs in the late 1970s and the 1986 rivalry between Nigel Mansell and Nelson Piquet.

The film is let down by an overlong running time and a prurient attempt to crowbar an emotional response from the taciturn Williams.

Frank Williams has his legacy well and truly besmirched in this highly unflattering and very juicy portrait.

This is a valuable addition to this year's 40th anniversary celebrations of Williams Grand Prix.

The title of Morgan Matthews's insightful film doesn't just refer to Frank Williams, the boss of the Williams Formula One team. This film transcends the remit of the sports documentary by also focusing on his late wife Virginia.

An affectionate but unflinching portrait of a family consumed by its dedication to Formula 1, thanks in main to its seemingly unstoppable patriarch, Sir Frank Williams.

It doesn't need to zoom around the tracks at 230mph - it patiently leafs back though a family photo album, rightly trusting in the human contours of the story more than the aerodynamics.

Sports documentaries tend to be very predictable. Williams surprises us by coming at its subject matter from an unlikely perspective.

Motor-racing may still be a man's world, but this account of a strong woman's triumph reveals a very personal and affecting hidden story.

Stories of obsession play well on the big screen, whether drama or documentary. And Sir Frank Williams' passion for going fast is particularly intense.
