i think all romance languages have a lot in common. knowing a bit of spanish, a lot of french, and next to zero italian, i was able to understand the GF films almost without ever looking at the subtitles.
i think the only thing missing from teh DVD collection is that i would have liked to see outtakes. there were some, during the screen testing for GF one, when FFC was trying so hard to get pacino cast in the film. but i would have liked to see others, possibly from GF 2 or 3.
