In its portrayal of a lovable but bumbling underdog, this old-fashioned British comedy rekindles memories of Norman Wisdom's Gump or School for Scoundrels, in which Ian Carmichael and Terry Thomas compete in increasingly juvenile games of one-upmanship.
Nick Frost, considerably bulkier than Wisdom, stars as Bruce Garrett, a downtrodden office worker who, years before, was a champion salsa dancer with "feet of flames".
Rashida Jones is the beautiful new American boss he wants to impress.
Chris O'Dowd is in enjoyably sleazy form as his office colleague, determined to seduce her first. The plotting itself is clumsy and predictable, and the sub-Office-style jokes are often flat-footed.
Frost himself, though, is an engaging screen presence. And the salsa sequences bring colour and energy to a film that would have otherwise been very listless, indeed.
