Yeah, released today it might not have that same mass appeal that it did 25 years ago. Although it still is just as funny today as it was back then. Plus all this animated stuff like Nemo and Lion King for kids, it wouldn't gross the $250,000,000 that it did back then. The 70's were different. Parents would drop their kids off at the theater for, I'm not kidding, the whole day and they would watch the movie a couple of times. You can't do that in this day and age and expect them to come back alive. Sad really.
One a side note in one of the scenes I noticed that gas was 56 cents back then... Can you imagine, 56 cents?
