A documentary “Unlawful Killing,” about the death of Princess Diana screened on Friday at Cannes Film Festival.

The film, directed by Keith Allen — father of the pop singer Lily, actor in “Trainspotting” and “Shallow Grave,” — earned a global disapproval for including a graphic image of Diana after the accident in 1997 – the details of which have historically been distorted in the interest of taste.

But the director defended the inclusion of the photo which he said within the legitimate context of tardy, inadequate care that Diana received tardy immediately after the wreck, and that more timely response would have saved her life.

Keith Allen has not announced if the film would also be screened in Malaysia. The film however could face cuts and more censorship if screen in the UK.
