Yoko Ono has reportedly filed law suit against the producers of an anti-evolution documentary film which used John Lennon's song Imagine without her permission, BBC reported.

The widow of John Lennon and her sons Sean and Julian sued the makers of Expelled: No Intelligence Allowed in a Manhattan federal court.

According to the 75-year-old Japanese artist and musician, the film gives the impression that she agrees with the ideas promoted by the documentary, leading to accusations that she was "selling out". The internet bloggers were the ones giving Ono a hard time for her alleged “licensing of the song to defendants," as the complaint said.

Premise Media, the producer of the film that challenges Darwin’s theory of evolution, rejected the accusations and argued that the "Imagine" segment is covered under fair-use copyright rules.

"Unbiased viewers of the film will see that the 'Imagine' clip was used as part of a social commentary in the exercise of free speech and freedom of inquiry," the produces said in a statement.

Yoko Ono and Lennon’s two sons are seeking unspecified damages as well as a ruling that would stop Premise Media, C&S Production LP and Rocky Mountain Pictures from distributing the movie that uses the song.

In the complaint, Ono added that Premise Media didn’t ask her permission to use the song because they knew they weren’t going to get it or because they did not want to pay for the rights.

Expelled: No Intelligence Allowed cashed in $3m (£1.5m) in its first weekend and it’s now at number 10 in this week's North American box office chart.
