Mark Hamill pranked hundreds of unsuspecting Star Wars fans on 3 December, as he headed down Hollywood Boulevard in Los Angeles dressed as a stormtrooper. The 64-year-old, who reprises his iconic role as Luke Skywalker in the upcoming sci-fi sequel The Force Awakens, once again donned the disguise he wore alongside Han Solo (Harrison Ford) and Chewbacca to rescue Princess Leia (Carrie Fisher) from the Galactic Empire's first Death Star in the 1977 original.

"I'm getting suited up in my stormtrooper gear, abut ready to hit Hollywood Boulevard for Force for Change," he says while suiting up. The stunt was done in association with Omaze, as part of the organisation's fundraising campaign for 15 charities chosen by the cast of the new Star Wars movie. Those who donate to the cause are in with a chance of winning tickets to walk the red carpet with the stars at the world premiere of The Force Awakens in Los Angeles on 14 December or the London premiere on 16 December,.

In the video, Hamill takes to the streets of LA to trick passers-by after a failed attempt at using the Force to open the hotel's lift doors. "Would you like to meet Mark Hamill?" he asks one oblivious victim, who enthusiastically replies: "I'd love to! That's the man, besides you."

It was not long before he encountered another person dressed as a Star Wars-inspired character, only this one happens to be villain Darth Vader (and Skywalker's infamous father). After a pretty intense stare-down between the pair, Hamill urges: "Just donate $10 – you don't wanna be a bad guy, do you?" To which Vader agrees: "Okay, that sounds like a very worthy cause."

During his antics, Hamill also got involved in a duel with a lightsaber-wielding Jedi Knight, asked a phone-accessory salesman if he "has any power converters" and a bus driver whether his route could take him to Alderaan. He even confuses Marvel character Iron Man as C-3PO.

Nearing the end of the clip, Hamill says: "Well that was something... I'm not sure exactly what, but definitely something," after he removes his helmet when safely back in his hotel room. "I couldn't be more proud of everyone in the Star Wars family. Your support has been absolutely fantastic, and I for one can't wait for the premiere. Right now its time for me to punch out and go soak in a warm tub."

Star Wars: The Force Awakens opens in UK cinemas on 17 December, with the film reaching US screens the following day. It will feature returning actors – Hamill, Fisher and Ford, plus Anthony Daniels, Peter Mayhew, Kenny Baker and Warwick Davis – as well as a host of new faces to the Star Wars world including Game Of Thrones' Gwendoline Christie, Andy Serkis, Lupita Nyong'o, Simon Pegg, Oscar Isaac, Adam Driver and leads John Boyega and Daisy Ridley.
