Mark Hamill congratulates boy on his BB-8-inspired prosthetic arm

Luke Skywalker lost an arm during a lightsaber duel in the beloved series.

An 11-year-old "Star Wars" superfan got a special message from Luke Skywalker congratulating him on his new BB-8-inspired prosthetic arm.

Cameron Miller, 11, from Ireland, was surprised with the custom "Star Wars" arm from the U.K.-based prosthetic company Open Bionics.

In video posted to the company's Twitter, Cameron says he was "really super, super happy" when he saw his new arm resembled the beloved droid BB-8 from the galaxy far, far away.

Actor Mark Hamill himself then responded to the video, congratulating Cameron for his "really cool bionic Hero Arm."

“They say you are a big #StarWars fan and I just wanted you to know that I am a BIG fan of yours & watching this video made me super, super happy!” he wrote, signing his note, “Your pal.”

In the film series, Skywalker lost his own arm during a lightsaber duel with Darth Vader, but never let that hold him back.
