A grubby, coming-apart-at-the seams, enjoyably tacky Brit flick on the theme of "aren't twins weird?". Primarily an excuse for showcasing the fag-end of London's swinging scene: a little bit dodgy, a little bit queer. Production design is a riot of 1970 hipster taste. All that sheepskin! Also features a bewildered and bewildering turn by Michael Redgrave.
