Alan Tudyk shared some behind the scenes details about “Rogue One: A Star Wars Story” in a recent interview. The actor plays the role of the droid K-2SO, and he shared how the requirements for this role led to a hilarious experience on the set.

Tudyk spoke at the Fan Expo Canada, in Toronto, to promote his new movie, Star Wars Underworld reports. The actor explained that the droid he plays in the movie is over 7 feet tall. The arms of the droid are “really spindle-y,” so they couldn’t use a suit.

The actor revealed that once they had to film a scene near a cliff. He couldn’t use stilts at this location, as there was danger of accident. The team came up with a backpack to solve the problem.

The backpack had a “head” that was of the same height as the head of the K-2SO droid. The backpack came to be known as the “backpack of shame” on the “Rogue One: A Star Wars Story” set.

Tudyk went on to reveal an interesting exchange between him and fellow cast member Diego Luna (Captain Cassian Andor). Luna apparently told the actor that what was happening with the actor was “terrible.”

Luna said that everyone on the set respected Tudyk, until he wore that backpack. The crew members felt “sorry” for the actor for having to endure such things for the film. Luna suggested that he should remove that “ridiculous” backpack, as it was upsetting everyone in the crew.

Tudyk, however, appears to be happy about having played the role of K-2SO in “Rogue One: A Star Wars Story.” He said that his character in the movie is another “in the line of great, great droids.” Just like the other droids in the franchise, the new droid has its own unique personality.
