The Hobbit Hurrah! Orlando Bloom Sings in Music Video Spoof, Ian McKellen Films Final Scene

Director Peter Jackson posts viral video and on-set photo of his actors as they wrap up their work on the big-screen adaptation of the J.R.R. Tolkien saga

Orlando Bloom and Ian McKellen are finished going there and back again.

Ten years after the British actors worked together on the Oscar-winning The Lord of the Rings trilogy, both have now wrapped up their work on the final two installments of Peter's Jackson's three-part adaptation of J.R.R. Tolkien's The Hobbit saga: The Desolation of Smaug and There and Back Again.

The cast and crew have been hard at work in New Zealand shooting the films back-to-back, and in a fitting tribute to his stars, Jackson said goodbye to both Bloom and McKellen in high style.

Or—at least in the case of Bloom—through song!

The director has posted a video on Facebook of Bloom spoofing his Legolas character in a cheeky musical number.

In the clip, the 36-year-old actor holds up an iPad while a looped video plays on screen with his character repeatedly screaming, "They're taking the hobbits to Isengard!"

To give the ditty more oomph, Bloom begins to "sing" along with the clip, chanting, "To Isengard! To Isengard! To Isengard!"

(Even Gollum makes a brief appearance in the video spoof—how's that for backup?)

"A day after saying goodbye to Gandalf and Tauriel, it was time to farewell Legolas," the director wrote. "What a great day it was, with Orlando battling a serious Orc for all 12 hours of shooting—part of the Battle of the 5 Armies for the third Hobbit movie."

He added, "When we finally got the day done, we said goodbye to Orlando, had a couple of beers...and couldn't resist doing this!"

The director also said farewell to McKellen, who wrapped up his scenes as the wise wizard Gandalf.

On Friday, Jackson posted a photo of himself with the 74-year-old actor, whose pensive expression succinctly summed up the duo's emotions during the actor's last shooting day.

"Seconds ago we finished our last shot with Gandalf," Jackson wrote. "The end of an incredible adventure that began in 1999. I'm feeling very sad right now."

That adventure continues to be a lucrative one for Jackson and Warner Bros.: The first installment in The Hobbit trilogy, An Unexpected Journey, grossed over $1 billion worldwide, only the 15th film in history to do so.

The next entry, The Desolation of Smaug, arrives in theaters on Dec. 13, and There and Back Again will close out the saga on Dec. 17, 2014.
