Movie icon Steve McQueen's son is to return to the site of his father's Le Mans movie this weekend (06Jul14) for the classic car race, 44 years after his first trip to the track.

Chad MCQueen was just a boy when he joined his dad on location and now he's backing a new documentary about the making of the 1970s film, which resumes filming in France on Friday (04Jul14).

MCQueen: The Man & Le Mans, co-directed by Gabriel Clarke and John MCKenna, features stock footage of MCQueen on set as he strives to make "the ultimate racing motion picture".

It will include interviews with five-time Le Mans winner Derek Bell, David Piper, who lost a leg during filming, and MCQueen's co-star in the film, Sigi Rauch.

Chad MCQueen tells Wenn, "I remember my time as a boy on the set in Le Mans as though it were yesterday, so it is exciting to return. My dad set out to make the most realistic racing film ever, and it was one of the most personally important films in his career, which is why now, more than 40 years later, I believe he would have been proud that it has become one of the greatest stories about racing ever told."
