1SO which films make up Gillian's Imagination trilogy?
Tsai's Walker films really has four: Walker, Walking on Water, Journey to the West and No No Sleep, but I'd count the first three as a trilogy. Still, I won't put it on my list because who knows how many he'll make in his "retirement".
What is the Golden Heart trilogy?
I haven't seen the movies per se, but isn't it strange that Abbas Kiarostami’s Koker trilogy hasn't been mentioned once?!
