Having fun on interviews

Had another interview today and was asked "whats you're favorite movie?"
No i didn't apply to blockbuster, the hiring manager and i just got along pretty well so questions were pretty casual and he just wanted to know me.
Anyways, I wasn't thrown off on the question, I immediately said "Star Wars," he responded "a new hope?" I nodded yes, and then he asked Why? I said "because its awesome." Then he was kinda suprised and said 'wow, you said that with no hesitation' hahahahaha! needless to say, he was impressed and I wouldn't change what I said.
