Although everyone got off the subject debating whether LOTR was comparible to Titanic, I have chosen to answer the first question.  The reason why that film isn't on the top hundred is probably because it is still in English.  Regardless of what country produced it, I still view a film in English as American, or non foreign.  If we did make these distinctions then British films like Lawrence of Arabia and A Clockwork Orange could make the list, going against what is a foreign film anyway.  Aside from that LOTR was just pretty good.  For my money Dead Alive and Heavenly Creatures, and to a lesser extent Meet the Feebles are the best Peter Jackson films.
