The last reply posted is right on the money. I screened both films at my house when "Vanilla Sky" came on DVD, and they are both essentially the exact same. You won't receive any new insight or revelations from watching "Abre los Ojos" if you've already seen "Vanilla Sky". 

No offense, but I think that if some people on this message board saw the same film of paint drying twice, and one of them had subtitles, they'd call it a masterpiece.
