As for HAKHK doing 650 crores...
It doesn't work like that. PK/3I would have done humongous business and recorded record footfalls perhaps even bigger if it came back in 1990's/80's. I can make that argument as well.
This is the problem with comparing across eras. There are are way too many factors involved to arrive at a suitable conclusion. Fan-boys like to come up with such ridiculous comparisons to suit their agendas..
Inflation, Piracy, poverty, Internet, DVDs, TV etc. There are just way too many variables going against getting people in the theaters in such numbers. The economics and ground realities are different that what they used to be.
Adjust the gross for all such factors and then come up with a figure. If you can do so, then we will talk about the merits of the said movie doing 650 crores.
