The longest I've ever lined up for a film was in May of 1980 when I went with friends to see The Empire Strikes Back.
The grand but long-gone University Theatre here in Toronto was the place to see a 70mm presentation of a big release. The way fate worked was the three hour wait in line to get tickets and the subsequent two hour queuing for 'ticket holders' was well worth it.
The Empire Strikes Back, to me, is the greatest Star Wars movie.
I had forgotten about Star Wars. What a nice dilemma to have....
