While Henry Cavill's first look as Geralt in the TV adaptation of The Watch MidhunterWitchervideo game did not go down well, his Aquaman impression can stay.

The Justice League star posted a congratulatory Instagram to his superhero co-star Jason Momoa by channeling his box-office smash Aquaman.

Cavill, who's usually seen donning a cape as Superman in the DC Extended Universe films, instead took to a body of water — in what weirdly looks like the dead of night — capeless, Lycra-less, and wielding a fork as a trident.

"Channeling the man of the hour, the man of big hugs, big laughs and big pints of Guinness, my man Jason Momoa. How'd I do?" he captioned the post.

"Seriously though," he added, "I just finally got the chance to watch Aquamanhere in Hungary. Jason, James and everyone involved in that movie, smashes it out of the (water)park.

"Jason, love you bro, you crushed it."

Aw. And he's right, financially and somewhat critically, with Aquamansmashing box offices around the globe, earning over $822 million and just overtaking fellow Justice League member Wonder Womanin global box office total (Patty Jenkins' film earned $821.8 million globally).

Aquamankicked the crap out of Justice Leagueat the box office, but hasn't quite smashed 2016's Batman v Superman: Dawn of Justice, the highest global box office DC Extended Universe film.

Momoa responded to the post with: "Thank god u were already casted for Superman. I'd be out of a job love u brother. Mahalo for the support."

Cavill's future as Superman remains relatively unclear, with rumours of his departure from the franchise met with rather vague responses from the star himself and Warner Bros in September.

But Momoa took it upon himself to put the rumours to bed at the Aquamanpremiere at Hollywood's TCL Chinese Theatre in December, saying Cavill was "absolutely not" leaving the role.

"I just talked to Henry ... He's absolutely not [leaving the character]," he told ET's Melicia Johnson. "He loves the character. He's not. One hundred percent."
