In the picture, Monaghan, who played Meriadoc Brandybuck, is joined by fellow hobbits Billy Boyd and Elijah Wood. Also in on the reunion? Non-hobbits Orlando Bloom, who portrayed Legolas, and Aragorn himself, Viggo Mortensen. While Monaghan's caption, "They have a cave troll," might be a deep cut for those unfamiliar with LOTR lore, the pose and "weapons" make it clear that the team is ready for a battle. Where was the rest of the fellowship? Sean Bean, Sean Astin, Ian McKellen, and John Rhys-Davies were nowhere to be found, but surely it's tough to get so many elves, hobbits, and wizards under one roof (when there's not a universe-shattering battle to be had, at least). The pic is giving us all the feels — the OG Lord of the Rings film was released 15 years ago last December — and we're not alone. Many of the cast members pictured in Monaghan's post participated in a retrospective interview in Empire , and according to Entertainment Weekly , Bloom posted a slew of behind-the-scenes pics from the film on his Instagram. Check out more pics from the impromptu reunion, below.
