Game of Thrones actor and Marvel star Jason Momoa has defended Will Smith, describing him as an amazing human being despite controversy surrounding his slap of Chris Rock.

Momoa was sitting in the front row when Will Smith stepped up to the stage and slapped Chris Rock in an incident that stunned the world.

"It's just people, we're under a microscope," said Momoa.

"I don't know what really it was for him, but he's an amazing human being. Both of them [are] and they'll work it out."

Momoa shocked by Will Smith slap

A joke from Chris Rock regarding Will Smith's wife, Jada Pinkett, prompted the latter to slap the Oscar presenter at the 2022 Academy Awards.

Facing backlash from the public, Will Smith subsequently resigned from the Academy and was banned from attending Academy functions, including the Oscars, for 10 years.

Momoa suggested people should consider Will Smith's mental state on the day as it may have played a role on his decision to slap Chris Rock.

"I was pretty shocked," added Momoa. "You just never know where people are at, you know? There's a tipping point for everyone, right?

"I've had my places. He can ask for forgiveness. Sometimes you're just sensitive. We're all sensitive. I'm not walking in his shoes, [but] I've definitely been in places like that."
