The Kevin Bacons of Bollywood?

I have seen 3.5 Bollywood films. Three of them have had the same person in them, and two of those have had an additional principal in common. Is this statistically usual? Or does the person who develops the collection of my local video store, That's Rentertainment (the best video store ever, by the way), suffer from some serious crushes?

Abby and I watched Chalte Chalte on Monday. V enjoyable but not as catchy to me as Kuch Kuch Hota Hai, although I appreciate its representation of the tribulations of maintaining a relationship past the happy glow stage. Or, as I said to Abby, "That's what happens when you marry someone you've only known for 24 hours."
