Although I've seen this movie many a time, I'm still completely involved every time I watch it. During the plane chase, I get nervous, and I (along with a few other people) screamed when the plane collided with the truck and exploded.
After the end of the movie, a discussion was again led about gender roles, sexuality, obsession, and masochism. It was also touched upon that Vertigo was recently voted the greatest film of all time, thus beating out Citizen Kane, by Sight and Sound and the semi-controversy/uproar/hooplah that caused. Again, the discussion was pretty interesting, and the audience was willing to participate.
Whenever I see a classic film in a theater, I am always surprised by the incredible turnouts. The ages always range from the very young (when I went to see Singin' in the Rain, I saw a couple of kids that had to be kindergarten age) to the old. I like to imagine that the older couples I see went to see the film when it was first released, possibly on a first date. It's really nice to know that these films still have an audience and that people are passing on their love of classic cinema to future generations. Here's hoping they never stop.
