Comedian John Oliver has teamed up with Helen Mirren to draw attention to the US Senate Intelligence Committee’s report on torture.

Oliver had the award-winning actress read from some of the more graphic sections from the report during the 15-minute segment on his Last Week Tonight show.

The British comedian draws attention to the fact that 57 per cent of Americans (according to CBS News) believe that torture is an effective approach that provides information that prevents terror attacks.

In comparison, only 46 per cent of the US apparently believes in the Big Bang Theory.

The depressing segment, occasionally partially lifted by Mirren’s twisted rendition of Beatrix Potter’s The Tale of Peter Rabbit, underlines the common misconceptions surrounding torture and its effectiveness.

It also provides a bleak insight into practises including “rectal rehydration” and the horrendous treatment of US prisoners, or detainees.
