Jaaneman had 2 superstars and was a love story wid a happy ending which is a universally appealing genre. While Don was a slick action film which appeals to youth(class youth, not mass youth) only. Still d collections were-
Don - 51 cr hit
Jaaneman - 20 cr flop
So, never underestimate SRK. Agar usne thaan liya toh Sultaan ko maarte-maarte Bihar chhod ke aayega.....
