The 68-year-old actor has provided an update on the flick, which will not only seen him reprise his role as LA police officer Martin Riggs in the buddy cop franchise, but also take the helm following the passing of original director Richard Donner in 2021 aged 91.

Appearing on the 'Inspire Me' podcast, he spilled: “I’m going to direct the fifth film in the Lethal Weapon series.

“Richard Donner, who did the other four, sadly passed away and he was a good friend. He kind of tasked me with carrying the flag home on that one so it’ll be an honour for me to do that.”

They've been working from the unfinished script Donner left behind.

The 'Passion of the Christ' filmmaker said: “We’ve used what was there and we kept kind of poking at it and working at it. I’m pretty happy with it. It’s good, I had a lot of fun doing it.

“It’s funny, but it’s pretty serious too. It tackles a couple of hard issues. I’m looking forward to it.”

In 2022, Gibson revealed that changes behind-the-scenes at Warner Bros. led to delays on the new film, which will also see Danny Glover return as cop Roger Murtaugh.

The 'Braveheart' star told Screen Rant: "The only delay is now with all the shake-up at Warners, with Discovery coming in and the new boss, and they chop everyone else up and throw them away and get new people.

"It always takes time for these companies to regroup, so that's been a delay, but I'm pretty confident we'll get this one up on its feet, probably shoot it in the first quarter of the New Year."
