Yeah, it's kind of absurd. This is the most popular film EVER MADE. EVER. Gone With the Wind sold more tickets, but it's no longer current.
-1977: Star Wars is released. Makes the equivalent of $1.13 BILLION dollars in todays currency.
-1978-1983: Goes on to earn roughly another $100 million dollars in todays money in re-releases over the next five years.
-1982: First VHS tape to sell over a million copies. Retails for about $80, or $180 in todays dollars. =over $180 million.
-1995: Released on video. Breaks records for a video re-release.
-1997: The twenty-year-old film is released again and earns $240 MILLION in todays dollars.
-2004: Released on DVD in trilogy set. The OT sells $100 million dollars worth of copies...in a SINGLE DAY. Goes on to selll...maybe a Billion dollars worth by Christmas? Just an estimate.
-2012: George Lucas is worth something like $4 Billion dollars. "It's too expensive to restore them! How would I earn a profit"
Reminder: the above figures add up to about something like the equivalent of... nearly $3 Billion dollars? Something in that range. A movie that has sold $3 billion worth of sales, in todays dollars. Yeah, there's no money there. It would be such a wasteful investment.
