For 2003: Lord of the Rings (both Fellowship and Two Towers)
For FOTR,I've watched the Extended DVD for about 4 times this year. Yung Two Towers naman, 3 times. 1st time was just to compare the movie (again) with the book (that I just finished the night before). The 2nd time was when I purchased the Two Towers Extended Edition (parang marathon!!). The third time was the same as the 2nd, but this time with the whole family watching (actually, ako nag-eexplain sa kanila ang nanyari habang nanonood sila). The last time was just before I watched ROTK sa moviehouse.
I usually make it a point to watch some of my collection at least once a year (para naman di sayang ang pangongolekta ko).
