Film premieres at Cannes Film Festival embroiled in legal battle.

"Colossal," Voltage's film which premiered at the Cannes Film Festival, is embroiled in a copyright infringement lawsuit for the unauthorized use of the Godzilla character.

In a complaint filed in a California state court on May 19, Toho – the Japanese company that holds the rights to the "Godzilla" film series – claimed that the filmmakers of "Colossal" produced, promoted, and marketed a Godzilla film without permission.

The company included in its lawsuit the content of an interview with director and screenwriter Nacho Vigalondo conducted in August 2014, in which Vigalondo asserted that "Colossal" would be the cheapest Godzilla film ever made.

This is an image of the Godzilla monster from 2014.

In the aforementioned complaint, Toho also accused the filmmakers of sending a series of emails on May 9th to potential investors, sales agents, and distributors to promote "Colossal"; and criticized Voltage for intentionally using the Godzilla character to draw attention to "Colossal," making the film stand out in a highly competitive environment.

Toho also accused Voltage of frequent copyright infringement. The company, owned by producer Nicolas Chartier, was previously sued for copyright infringement of the 2010 Oscar-winning film "The Hurt Locker" and the film "Dallas Buyers Club" four years later.

Another detail mentioned in the lawsuit is the image of Tokyo, Japan, being attacked by Godzilla, which was printed on promotional leaflets and posters for "Colossal" at the Cannes Film Festival.

The film "Colossal" stars Anne Hathaway as a woman who suddenly finds her mind strangely linked to a giant lizard destroying Tokyo. However, this lizard bears a striking resemblance to Godzilla from the film of the same name, for which Toho holds the rights.
