Golmaal 3 is being hyped as the ‘First Indian Trilogy’. It is a complete lie. It maybe the first bollywood trilogy but it is certainly not the first “Indian Trilogy”. I know of at leasttwothree malayalam trilogies and other languages may have had other trilogies. (If you know of any please leave a comment) The trilogies in Malayalam areh4. CBI Diary Kurippu Series
EDIT: More Trilogies Apu Trilogy in Bengali (via gobbledyspook )
