Everything's changed. The technology is the big thing changing now, the way movies like 'Alice' or 'Avatar' are made. And technology on the other side, the audience side. Word spreads so fast now on a movie, with the Internet, and piracy is something coming down the line like in the music industry.
The technology is really where all of the changes have taken place, but the fundamentals of a good story being the basis of every good picture, and really the only basis still remains the rule, more so today, I think, because we've unfortunately weaned an audience from birth to kind of mindless movies.
