When it comes to that greatest of British cultural exports, the punk rock movement, figures don’t come much bigger than Ian Dury, so when we at Best For Film learned of the release of a Dury biopic starring the fantastic Andy Serkis, we were psyched. Serkis is spellbinding in his complete embodiment of the eccentric, mercurial rock star, but it’s almost too good a performance for his support cast to hold their own against. Mat Whitecross’s patchy and confusing narrative also leds proceedings down sufficiently.
