Watch: Mel Gibson and Danny Glover hanging out on stage makes us pine for Lethal Weapon 5

You can fake scenery, explosions, aging - whatever. You can't fake chemistry and that's exactly what Mel Gibson and Danny Glover have, as evidenced from this.

In a tribute to the career of Richard Donner - who we interviewed last year, along with his wife Lauren Shuler Donner - Gibson and Glover took to the stage and basically reminded us why Lethal Weapon is the defining buddy-cop film and what easy, natural chemistry looks like.

As well as this, you can see Glover and Gibson really are truly passionate about Donner's work and what a skilled director he was - and why he absolutely needs to make a Lethal Weapon 5.

Take a look.
