I don't know how the hell Jack and Desmond didn't eat shit when running up and down the stadium stairs. Aloha Stadium's stairs are so gat-damn steep, I don't know how many times I've fallen on my ass there.

All the airport flashback scenes aren't filmed at an actual airport -- but at the Convention Center.

And the "hatch" and "cave" scenes? Their soundstage is at the former Xerox building 10 minutes away from my house -- where 7 Xerox employees were gunned down in 1998. The cast and crew have reported weird things going on during filming. Can you imagine filming suspenseful scenes and having to deal with ghosts? Must be creepy!
