Well, the winner in the difficult category of Favorite 3-D effect in Purana Mandir 2, aka Saamri, aka 3-D Saamri, was as follows: lecherous bad guy is flirting with an attractive maid at the haunted bungalow, and tries to stall her by offering her an unpeeled banana (hmmm). This provides an opportunity to thrust the banana toward the camera a few times. That's got the yo-yo scene from Friday the 13 Part 3: 3-D totally beat.
I also discovered that this whole time, I've owned two separate Hindi-language films with full-on zombie graveyard dance scenes openly inspired by "Thriller." (In this case, it's all a dream by Jagdeep as cook/gravedigger "Chunges Khan alias Startrek," who actually says "Michael Jackson, Thriller!" afterwards, although Mithun looks better in the shiny red jacket).
