Not just people you think would be there but everyone. From the Matrix to Batman to the Hulk was at the 35th annual event.... an event that when it was first conceived was about comic books but has expanded to movies, TV and other mediums.
Is it a geek fest?? Maybe... non-geeks like super heroes too, just see the gross take for Spider-Man 2. Some movie studios have used the Comic - Cons event to test what new movies to come up with. This even is pretty big considering that 75,000 people came to it last year.
And yes the Klingons were there too.
