Keeping it casual: Keanu Reeves, 57, cut a casual figure in a leather jacket and cosy beanie as he stepped out in Paris for the filming of John Wick 4 on Friday

The star had on a pair of beige lace-up boots and could be seen stepping into a chauffeur driven car before he whizzed off to set.

Keanu’s long black hair was poking out from underneath the hat and he was sporting a smattering of salt’n’pepper stubble.

The fourth addition to the John Wick franchise is due out May 27 next year.

His outing comes as anticipation for The Matrix Resurrections, the surprise fourth instalment in the science-fiction franchise, has begun with a new poster teasing the release of its first trailer.

The film comes 18-years after The Matrix Revolutions, originally intended to be the final chapter in a trilogy documenting the transformation of computer hacker Thomas Anderson into cybercriminal Neo after he inadvertently discovers the ordinary world he inhabits is a simulated reality.

Stretching out the anticipation, fans were treated with an ad for the promotional launch featuring red and blue pills sat side by side beneath the stark message: ‘The choice is yours.’

‘The choice is yours’: Stretching out the anticipation, fans were treated with an ad for the promotional launch featuring red and blue pills sat side by side

Fans of the popular franchise will recognise the pills as a decisive option given to Neo, played by Keanu Reeves, as he chooses between life in the war-ravaged real world or the ‘beautiful prison’ of alternate reality.

Piercing static serves as the backdrop, as tiny strings of Matrix code are seen falling down inside the pills before the entire scene melts.

The trailer invited fans to continue their saga on WhatIsTheMatrix.com, an interactive choose-your-own-adventure style site.

Presented with the same choice there, red takes you down a rabbit hole where you’re told: ‘This is the moment for you to show us what’s real.’

Then scenes from the film flash, showing the thin barrier between reality and the artificial world known as The Matrix.

‘This could be this is the first day of the rest of your life, but if you want it, you gotta fight for it,’ the narration wraps while showing star Keanu Reeves ready to fight.

Picking the blue pill offered another path, asking viewers: ‘Do you remember how you got here?’

‘You’ve lost your capacity to discern reality from fiction,’ the narrator says before several surreal scenes flash by.

‘What’s real is here and now… Anything else is just your mind playing tricks on you.’

‘It becomes a problem when fantasies endanger us,’ they warn as someone is seen pouring out a bottle of blue pills.

Then, ending on a sinister note, they show someone touching the computer port at the back of their head and ask: ‘We don’t want anyone to get hurt, do we?’

The original Matrix feature was released in 1999 and was met with much critical praise upon its debut. The feature was followed up by two further films, which were both released in 2003.

The Wachowskis, who directed all of the entries in the series, initially had no plans to continue the franchise after the third picture’s debut. However, rumors about a potential fourth film began to circulate in the early 2010s.

The Matrix Resurrections is set for a December 22 release.
