He was caught on video applying for a marriage license at a Las Vegas courthouse on Saturday in a somewhat agitated state.

And now Nicolas Cage has filed legal documents seeking an annulment of his four-day marriage to girlfriend Erika Koike who also agrees that it was a 'mistake.'

TMZ reported Thursday that the Leaving Las Vegas Oscar winner asked a judge Wednesday to void the nuptials.

Cage, 55, and makeup artist Koike are believed to have started dating a year ago.

The Blast has since reported that Cage is not the only one who believes tying the knot was not a great idea as his new wife agrees and will not fight the annulment.

Sources told the publication that Cage believes the entire situation was a 'mistake.'

In footage obtained by DailyMail.com, Cage was filmed making a scene while applying for a marriage license with his much younger girlfriend, bizarrely telling onlookers she was going to take all of his money.

The couple were spotted at the Clark County Court House Marriage Licence Bureau in downtown Las Vegas around 11 a.m. on Saturday and Cage appeared to be 'very out of it' and was 'most likely drunk', an eyewitness told DailyMail.com.

At one point, the nephew of The Godfather film director Francis Ford Coppola raised his voice and started shouting about how Koike's 'boyfriend' is a drug dealer and that 'he isn't doing it' - seemingly referring to getting a marriage license.

The video shows Koike calmly telling Cage: 'I never asked you to do this', before he smiles and gently pushes her through the hallway, saying 'come on, let's go'.

'They started by filling the application in one of the machines,' the source told DailyMail.com. 'The whole time he was yelling 'she is going to take all my money' and 'her ex is a druggy, her ex is a druggy'.'

'The woman only kept saying 'Baby, I am not asking you to do this',' the source added.

Because the couple were making such a scene, they were taken into a private room and later left the courthouse with papers, according to the source.

The Con Air and Face/Off star was first spotted with Koike last April while he was filming in Puerto Rico.

They've been seen together a few times since, including heading to dinner together in Beverly Hills in May 2018, but have mostly stayed out of the spotlight.
