Also, I think it's funny that even after he knows she's just in his imagination, Milo still keeps his dinner date with Sally. Couldn't he have called her Durden phone and rescheduled their date to the relative privacy of his mom's basement?

I do not at all believe that Phillippe was under the mask in all those scenes. In fact, I don't think he was even on set unless it was a scene where you saw his face.

According to IMDB, Ewan McGregor, Paul Bettany and John Hurt were once set to star as the film's three main male characters. That probably would have been a much better movie, although I doubt it would have been enough to get me to look past the lousy script.

Um yeah, where the hell was he hiding that giant sniper rifle all this time? When they said "service weapon" I was expecting a handgun. And if the military guys knew he still had it, why hadn't they taken it back yet? Did they just look at the Massive Rifle Sign Out sheet and all of a sudden notice he never brought it back? Totally ridiculous.

Spotting when the audience is being set up for a "this character doesn't really exist" moment is one of my favorite little distractions while watching movies and TV. In the scene when Milo and Sally are talking through the chain link fence, the shot where the fence is filmed at such an angle as to completely obscure Sally was a dead giveaway.
