EGR101March 27, 2012Judging from the response to the trailers, PROMETHEUS should open big, $80-120million range is not unattainable. At its worst, it will do TRON LEGACY type of gross: $50 mill opening/$170 million final gross. TRON 2 has superb trailers but very weak plot in the second half. At its best? $250 million, that's about the US gross in current dollar if the original  ALIEN opens today. A smart, exotic action science fiction which is rated R, MATRIX RELOADED, did about $300 million in 2003. PROMETHEUS may do that kind of number if the fundamentals (story, action, characters) are strong.
