Sitting outside a studio in Brooklyn, New York on Thursday afternoon, Keanu wore a red cap over his long straggly hair.

On top of the bushy beard, Keanu wore a hoodie underneath a black coat, jeans and walking boots as he smoked a cigarette and drank a shake.

Sitting out of the sun, Keanu kept himself to himself as he chilled out on a chair, taking a break from training for the physically demanding role.

At one point, the Bill and Ted star took his shoes off to rest his feet.

Keanu first starred as titular character John, a retired hitman, in 2014, with the sequel dropping last year.

Both were critically-acclaimed and amassed a combined $260 million at the worldwide box office.

Earlier this year, Keanu revealed he regrets not sleeping with more adoring female fans.

The Canadian actor said that after starring in River’s Edge he would have knickers thrown at him – but did not often act on it.

The Matrix star said: “I probably should have taken more advantage but I didn’t.

“You know, I was a little self conscious about that. I mean I’m not saying it didn’t happen sometimes.”

He also admitted in the Esquire interview that he very nearly died in a motorbike accident.

The star said he took a hairpin bend too fast and lay on the pavement for half an hour thinking he was going to die.

The accident left a thick scar up his abdomen and necessitated the removal of his spleen.

He also had surgery for fake teeth, veneers and some broken ribs.

Reeves added: “You know, it’s weird. After the accidents the adrenaline kicks in, so it’s not really painful. Maybe the broken ribs part. That was pretty uncomfortable.”
