The Boulting brothers' satire on industrial relations hasn't dated that well politically, since it alternates between slap-on-the-wrist jokes about management, and vicious jokes at the expense of trade unions.
Ian Carmichael, reprising his role from Private's Progress, is weedily decent as the toff who takes to the shop floor to see how the other half lives, but the lasting fame of the film is down to Peter Sellers' Fred Kite, a bolshy, work-shy shop steward, intent on shouting 'all out, brothers' at the slightest provocation. An array of British comic talent includes Margaret Rutherford, Dennis Price, Terry Thomas and Liz Fraser.
