The last time we heard of a fifth 'Lethal Weapon' movie being in the works was back in 2017. There's been a TV series, which ran from 2016 to 2019, in the interim.

Now, at long last, it looks like 'Lethal Weapon 5' is back on the cards. And both Mel Gibson and Danny Glover are up for it.

The original 'Lethal Weapon' movies saw the actors play mismatched LAPD detectives Martin Riggs and Roger Murtaugh. They are two of Gibson and Glover's most renowned roles and the pair made four films based on the characters between 1987 and 1998.

They reunited 3 years ago alongside co-star Rene Russo. It was at that point the rumour mill starting churning about a fifth instalment, with director Richard Donner returning too.

The latest developments saw producer Dan Lin indicate that it's very much in the pipeline.

Lin, who worked as exec producer on the 'Lethal Weapon' TV show and has been a producer on such films as 'It', 'The Lego Movie' and last year's 'Aladdin', revealed all at The Hollywood Reporter's Producers Roundtable, hosted by journalist Rebecca Ford, and attended by fellow producers Emma Tillinger Koskoff, Debra Martin Chase, David Heyman, Peter Chernin and Charlize Theron.

Lin said Warner Bros. are developing a fifth movie in the action comedy franchise. He said Glover and Gibson are attached, with Donner expected to return. He also stated this outing would likely be "the last" for the crime-fighting duo.

"We’re trying to make the last 'Lethal Weapon' movie," he told the panel.

"And Dick Donner’s coming back, the original cast is coming back. And it’s just amazing. The story itself is very personal to him. Mel and Danny are ready to go, so it's about the script."

Both Gibson and Glover have been busy making movies of late. Last year alone, Glover starred in 'The Last Black Man in San Francisco', 'The Dead Don't Die' and 'Jumanji: The Next Level'; Gibson starred in 'The Professor and the Madman' and 'Dragged Across Concrete' in the last couple of years and is also returning to directing with a sequel to 'The Passion of the Christ'.
