Romain Duris, looking like a wolfishly unkempt Mick Jagger, plays an undercover seducer hired to lure women out of bad relationships. To break up the engagement of a sexy rich girl (Vanessa Paradis), he poses as her protector. Heartbreaker is like a caper comedy meets The Bodyguard — it's winsome and accomplished fluff. Duris has to pretend to love Dirty Dancing, and the whole film is really his and Paradis' love tango
