3. The Lord of the Rings: The Return of the King
When you create a series of movies as dense and expansive as those in Peter Jackson's
Lord of the Rings trilogy, a few mistakes are bound to slip in, which is why we can look at this particular instance of unexpected crew cameoing and laugh. During the the final sequence when hundreds of orcs start to surround Aragorn and company at the Black Gate, keep your eyes peeled for a brief shot of two orcs shifting position to the left - in amongst them, you can glimpse a hairy looking crew member who has clearly been sent into battle against his wishes!
