It didn't help that the 29-year-old actor was donning a coat of fur under his dapper suit.

“I’m a hairy man,” said Jai, who revealed he had to make some changes for the film, “They made me shave my chest.”

But, Jai is keeping his bushy facial hair for his role as Captain Boomerang in the upcoming DC super-villain film Suicide Squad.

“I’m playing an Aussie, so I’m just letting it all grow,” said Jai.

Terminator Genisys is in theaters now.
