Watch on Soap2day. A documentary following US, Peter Brook's experimental play about the moral issues surrounding the Vietnam War, Benefit of the Doubt is the only known film record of the Royal Shakespeare Company production. It was filmed by Peter Whitehead concurrently with his Tonite Let's All Make Love in London (1967), on the surface a very different film, yet both share a central concern with the war, protest and Britain's political and cultural relationship with America.
