Trying to coordinate x number of friends to watch a movie session over the net, would be quite a logistic challenge. Timing with random people over chat rooms would be more probable but movie watching with such a crowd would be too creepy and sinister. Twould be like sharing popcorn with the guy sitting next to you in the theatre and strangely discovering something rubbery hard at the bottom of the paper bag. Your only next chilling thought being I can't believe its not butter.
Mentioning popcorn, I think Cesar Romero would be the best joker. There's a few websites with people that agree with my thought. The Joker faithful to the comic books was creepy but at the same time jovial with a touch of cynicism as he planned the death of his victims leaving behind chemical trademark that would mold the victims face to be like his...
The Joker was creepy, Jack nicholson was just a creep. So although Jack was quite fitting for the role, he was just acting as himself. Heath ledger, I can't say yet, but with the trailer, he seemed really dark and sad.
So i vote Cesar Romero, if he was young enough to be todays evil villain, i think the CGI and makeup would have complimented well with his jovial and cynical laugh.
