Diego Luna still gets ''chills'' hearing Darth Vader breathe.

The 36-year-old actor stars as Captain Cassian Andor in the upcoming spin-off to the popular 'Star Wars' franchise, 'Rogue One: A Star Wars Story', and admits he is still deeply fearful of the Sith Lord.

Asked if he is still afraid of Darth in an interview with HeyUGuys.com, he said: ''If I hear his breathing I just get the chills. I've been like it since I was like six. Even back then I knew what was going on.''

Meanwhile, the 'Dirty Dancing 2' star previously spoke out about how the film is ''a beautiful film about unity and celebration''.

He said: ''It's a clear message what this rebel group sends... By leaving differences aside, we can be stronger. By celebrating our differences and understanding that those differences make us richer and stronger and more powerful we can do whatever we want, you know? There is no limits. It's a beautiful film about unity and celebration.''

But it's almost a movie that Diego didn't get to be a part of at all, as he recently admitted he nearly missed a phone call from director Gareth Edwards offering him the role.

He said: ''I saw this British number calling me at 2 a.m., and I have family in England, so I thought it was, like, a drunken cousin from a bar or something.

''I ran over and saw that it was Gareth Edwards wanting to give me some news! I just jumped around like crazy - it was quite a special day. [Edwards] said, 'Okay, welcome to Star Wars.'''
