A surprise hit documentary about penguins has overtaken Amelie to become the second most successful French film at the North American box office.
The film follows the annual breeding habits of the Emperor Penguin
The Fifth Element remains France's top film, making $66m (£36m) in 1997.
March of the Penguins made $6.8m (£3.7m) at the weekend, taking its box office total to $37m (£20m).
Luc Jacquet's film about the penguins' mating season is also the second most successful documentary in US box office history after Fahrenheit 9/11.
Michael Moore's film - which criticises President Bush's handling of the terrorist attacks of September 2001 - became the first documentary to make more than $100m (£58m) at the North American box office in 2004.
March of the Penguins has surpassed Moore's Oscar-winning documentary, Bowling for Columbine, which took $21.6m (£12m).
The documentary follows the annual journey of Emperor penguins as they march single file to their traditional breeding ground in Antarctica.
In the French version of the film - which was shot by a four-man crew over 14 months - actors' voices speak for the penguins.
But it was felt by distributors that the style would not appeal to English-speaking audiences, and in the US version the voices have been replaced by a narration by actor Morgan Freeman.
