Here in the UK, Star Wars did not arrive until Christmas 1977. It went on general release in January 1978.
Before the film arrived here, many pictures and scenes from the film were appearing in magazines and on the television. I was collecting pictures even before the film came here.
I saw Star Wars sometime early 1978 aged 12 at Guildford Odeon in Surrey. I went back many times as the film was being re-released every school holiday.
So you’re saying you were a fan before the movie was even released (at least in your country). That’s awesome.
