Director Ken Russell gave Busby Berkeley a run for his money when he turned the hit Broadway musical about the Roaring ’20s into one of the most delightful gems of 1970s cinema. Here the play is being staged by a theatrical company, and shy Polly Browne must replace the leading lady just as a Hollywood big shot shows up for the performance. Brit “It Girl” Twiggy is perfectly cast as the reluctant understudy, who falls in love with her leading man and whose imagination sparks fantasy sequences that are among director Russell’s most delirious. The original one-sheet called THE BOY FRIEND “a glittering, super colossal, heart warming, toe-tapping, continuously delightful musical extravaganza” - it’s all that and more. With Tommy Tune.
