They became superstars when they starred in The Lord Of The Rings trilogy together from 2001 to 2003.

And Orlando Bloom, 41, staged a mini-reunion with his co-star Sir Ian Mckellen, 79, alongside The Hobbit star Adam Brown, 38, on Monday.

Meeting up in London, the trio were clearly very happy to see each other as Ian wrapped his arms around his pals' shoulders.

Keen to make his Instagram followers laugh, Orlando wrote in the caption: 'A dwarf, a wizard, and an elf walk into a bar.'

Orlando famously played the elf Legolas in J. R. R. Tolkein's fantasy, who used his skills as a master bowman to fight alongside The Fellowship Of The Ring.

Sir Ian, meanwhile, took on the role of wizard Gandalf the Grey, and later became Gandalf the White, who fought to destroy the One Ring.

The two actors later starred in The Hobbit trilogy, which itself was a prequel, where they reprised their roles as the elf and wizard.

In the hit films, the characters helped hobbit Bilbo Baggins (Martin Freeman) and a group of dwarves reclaim The Lonely Mountain from Smaug.

Adam played Ori, one of the dwarves who was part of Thorin's company and was desperate to get back his homeland from the menacing dragon (played by Benedict Cumberbatch).

This is not the first time that the actor reunited with a fellow Lord Of The Rings cast member, as Liv Tyler caught his play Killer Joe in London's West End earlier this month.

'Just a pair of elves 'n a pup,' Orlando captioned the snap, which shows the two of them and his miniature poodle, Mighty.

Liv also posted the image, writing: 'My dear @orlandobloom you were brilliant in @killerjoeplay !!!!!!! Love you !!! Elven family. Arwen and Legolas forever,' in reference to their characters in the fantasy epic.
