Obviously lots of things are different now than back in the day. Episode 4 maxed out initially at a little over 1,000 screens and the cost of a ticket was way less than today. The average ticket price for the original Star Wars was $2.23. Last I saw, the average movie ticket was $8.71 this year and the two recent movies played on 4,100+ screens. So basically, a ticket costs almost 4 times as much and popular films play on 4 times as many screens.
I guess it depends where you live, as a regular priced movie where I am costs $11.25.
