The parents of missing British girl Madeleine McCann have held talks with a U.S. entertainment company regarding making a film about their daughter's disappearance, their family spokesman said Tuesday.

Clarence Mitchell, who speaks for the McCanns, said he and another family representative had met with entertainment company IMG Media in December.

"If we feel any particular proposal in the media has validity in helping us find Madeleine, we are happy to discuss it," Mitchell said.

Mitchell said a film would be considered only if it helped raise awareness of the case, emphasizing that nothing had yet been agreed.

IMG spokesman Jim Gallagher confirmed that representatives of London-based Darlow Smithson, an IMG subsidiary which produces television programs, had met with McCann family representatives.

He said the company talked about the possibility of an observational documentary following the ongoing search for Madeleine, adding that discussions were still at an early stage and the issue of money had not been raised.

Madeleine McCann disappeared from a Portuguese resort on May 3, a few days before her fourth birthday. Despite a global campaign by her parents, the girl has not been found and no one has been charged over her disappearance.
