Michael Keaton has won a legal battle against producers of his directorial debut The Merry Gentleman after a judge dismissed their lawsuit on Monday (22Dec14).

In 2013, the Batman star was hit with a breach of contract suit by producers, who accused him of sabotaging their project by handing in his final cut of the movie late, fighting with them over which version to show at the 2008 Sundance Film Festival in Utah and badmouthing the film in Tv interviews.

The movie, which he also starred in, bombed at the box office and the producers filed the lawsuit to recoup the fee they paid Keaton, plus the entire $5.5 million (£3.4 million) they invested in the project.

Keaton's first attempt to dismiss the lawsuit failed last year (13), but on Monday (22Dec14) Illinois District Judge Gary Feinerman granted the request, ruling there was not sufficient proof that Keaton's alleged behaviour caused the poor box office performance.

Keaton's lawyer Michael Kump tells The Hollywood Reporter, "Michael is extremely gratified with the Court's decision to grant our motion and dismiss the claims against him... This lawsuit should never have been filed. Every person who worked on the film testified that Michael worked tirelessly and passionately to make the best possible film. The movie received widespread critical praise when it premiered at the Sundance Film Festival and later when it was released. Michael looks forward to continuing with his many artistic endeavours."
