Warner Bros has launched legal action against Donald Trump after he used music from The Dark Knight Rises in a tweet.
The US president, notorious for his often controversial use of the social media platform, posted a two-minute video for his 2020 re-election campaign which used Hans Zimmer's Why Do We Fall? from the 2012 film.
It also featured the film's title cards.
Following news of Warner Bros' legal action, the tweet was still available but the video had been replaced by a message stating: "This media has been disabled in response to a report by the copyright owner."
Mr Trump had captioned it: "MAKE AMERICA GREAT AGAIN!"
In a statement, Warner Bros said: "The use of Warner Bros' score from The Dark Knight Rises in the campaign video was unauthorised.
"We are working through the appropriate legal channels to have it removed."
Mr Trump, who entered the White House after beating Democratic candidate Hillary Clinton in 2016, has previously used pop culture references to promote his presidency.
During heightened tensions with Iran, he used a Game Of Thrones-style poster bearing the slogan "Sanctions Are Coming", a reference to the series' "Winter Is Coming".
And Mr Trump has also faced legal action over copyright issues before.
Artists including Prince, Pharrell Williams and The Rolling Stones have taken issue with the US president using their music at campaign rallies.
In 2008, former US President Barack Obama was asked to stop using a song by soul singer Sam Moore.
In a letter to the then-presidential candidate, the singer of "Hold On, I'm Comin'," asked him to stop using the song.
Mr Moore congratulated Mr Obama on his candidancy but said he had not "endorsed" him for high office.
Mr Obama agreed to stop using the song.
