Which A-list action star is climbing the Hollywood sign? Actor hoists himself up famous landmark while filming commercial

An A-list actor was spotted climbing up the Hollywood sign in Los Angeles, California on Monday. 

The action star was spotted hosting himself up the famous landmark as he filmed an Olympic-themed commercial.

A film crew were close by on the ground while flying drones captured every moment of the star's ascent. 

The actor put his years of experience in the action genre to good use as he showed off his buff physique in a tight black T-shirt. 

But can you guess who it is?

A film crew were close by on the ground while flying drones captured every moment of the star's ascent - but can you guess who it is? 

That's right, it's Tom Cruise.

The Mission: Impossible star, 61, looked in his element as he filmed the physically demanding commercial.

At one point, he was seen lifting his shirt and showing off his washboard abs as a crew member took a snap of him.

Tom completed his look for the commercial with black trousers and a pair of matching boots. 

Along with his new ad, Tom has been busy filming the next instalment of the Mission: Impossible franchise.

The actor is reportedly prepared to fly the cast and crew to Longcross Studios in the UK amid the M25 closure, to continue making progress on the blockbuster.   

Tom has been working at the filming location in Longcorss, Surrey this week to try and meet a 2025 deadline for the next movie, where he will reprise his role as agent Ethan Hunt.

Longcross is near junctions 10 and 11 of the M25 - where the motorway is closed this weekend.

'The M25 closure is a headache for most people but not for Tom. He is so keen to keep Mission: Impossible 8 in production that he’s got helicopters on standby in London to fly his crew over to Longcross,' a source told the The Sun.

'It sounds excessive but delaying work on the film is a bigger problem and Tom is such a professional — he’d move heaven and Earth to keep the show on the road.'

'Staff on the movie or stars who are needed for filming have been told if they can’t get to Longcross because of the M25 closures they’ll be flown in by chopper,' the insider added.

'It's a feat that is just like a scene out of one of Tom's films.'

Tom was seen filming last week in Derbyshire along with co-stars Simon Pegg and Hayley Atwell. 

MI:8 was supposed to hit cinemas this summer, but production has already been delayed due to the Hollywood writers' strike. 

The seventh film, Dead Reckoning Part One came out last year.

Cast and crew had been prepping for the huge shoot in Derbyshire, lasting around a week.

The Mission: Impossible film series, beginning in 1996, is based on a 1966 television series of the same name.

Production on the eighth film had originally halted so that the cast could promote Part One, and then the strike began causing further delays.

Along with Mission: Impossible, Tom is flying back into action for a new Top Gun sequel after the massive box office success of the previous entry.

Tom will be back as Captain Pete 'Maverick' Mitchell, and Paramount, which will be producing again, is hoping to reunite him with his recent costars Miles Teller and Glen Powell.

The news that Tom is back in business with Paramount — where he has released many of his recent films — comes just days after he signed up for a deal with Warner Bros. to produce and develop new films for that studio, including movies he'll star in.

According to Puck News, Maverick co-writer Ehren Kruger is writing a script for the third entry in the series.

Sources told The Hollywood Reporter that director Joseph Kosinski is also expected to return after proving himself with the critical and commercial smash success.
