Cotillard found herself in hot water recently over comments she made in an interview last year accusing the U.S. of a 9/11 cover-up.
"Marion never intended to contest nor question the attacks of Sept. 11, 2001, and regrets the way old remarks have been taken out of context," her Paris-based lawyer Vincent Tolesano told the Agence France Presse.
The actress made her comments on a French television program in February 2007, saying "I think we're lied to about a number of things," including who brought down the World Trade Center.
Cotillard argued that it was an inside job, prompted by the towers becoming obsolete.
"It was a money-sucker because they were finished, it seems to me, by 1973, and to recable all that, to bring up-to-date all the technology and everything, it was a lot more expensive, that work, than destroying them," she said.
The interview surfaced on a French magazine Web site and has made the rounds over the Internet.
Cotillard is due in Chicago next week to begin filming "Public Enemies" opposite Johnny Depp.
