Actor Jonathan Majors has arrived in a New York court as he’s set to be sentenced for assaulting his former girlfriend, a conviction that has already derailed the once-rising star’s career.

The actor, wearing all black and greeting supporters in court, faces a year in prison but could also just receive probation after a Manhattan jury in December found him guilty of misdemeanour assault.

Lawyers for Majors and Manhattan District lawyer Alvin Bragg declined to say ahead of the hearing what punishment they’ll seek from a judge.

Following the guilty verdict, Majors was immediately dropped by Marvel Studios, which had cast him as Kang the Conqueror, a role envisioned as the main villain in the entertainment empire’s movies and television shows for years to come.

The conviction stems from an altercation in March 2023 in which Majors’ then-girlfriend Grace Jabbari accused him of attacking her in the backseat of a chauffeured car, saying he hit her head with his open hand, twisted her arm behind her back and squeezed her middle finger until it fractured.

Majors claimed the 31-year-old British dancer was the aggressor, flying into a jealous rage after reading a text message from another woman on his phone. He maintained he was only trying to regain his phone and escape Ms Jabbari safely.

The jury ultimately convicted him of one assault charge and a harassment violation, though acquitted him on a different assault charge and of aggravated harassment.

Majors was originally slated to be sentenced in February, but his lawyers sought to dismiss the conviction. A Manhattan judge denied the motion last week.

Majors had hoped his two-week criminal trial would vindicate him and restore his status in Hollywood.

In a television interview shortly after his conviction, he said he deserves a second chance.

“As he eagerly anticipates closing this chapter, he looks forward to redirecting his time and energy fully toward his family and his art,” Majors’ lawyers said in a statement last week after losing their bid to have the conviction tossed out.

But the 34-year-old California native and Yale University graduate still faces other legal hurdles. Last month, Ms Jabbari filed a civil suit in Manhattan federal court, accusing the actor of assault, battery, defamation and inflicting emotional distress.

She claims Majors subjected her to escalating incidents of physical and verbal abuse during their relationship, which lasted from 2021 to 2023.

Majors’ lawyers have declined to respond to the claims, saying only that they’re preparing to file counterclaims against Ms Jabbari.

The actor had his breakthrough role in 2019’s “The Last Black Man in San Francisco”. He also starred in the HBO horror series “Lovecraft Country,” which earned him an Emmy nomination, and as the nemesis to fictional boxing champ Adonis Creed in the blockbuster “Creed III”.

As for Marvel, a looming question remains whether the studio will recast the role of Kang or pivot in a new direction.

Majors’ departure was among a recent series of high-profile setbacks for the superhero factory, which has earned an unprecedented 30 billion dollars worldwide from 33 films.
