Surprised not to see any Srk Movie in the list
I rate him as biggest Overseas tier 1 Superstar till date as it is there have been only 3- Raj Kapoor being 1st then srk and then Aamir being the last. Salman Can very well be the next one to join the list seeing how his performance improved in overseas.
It will be extremly difficult to replace Srk as all time no. 1, His Atg and Atbb record will be broken by Aamir till his career ends but BB records may or may not be broken and hits record out of reach due to less volume Of Aamir's movies.
Talking about Dangal be it adjusted or non adjusted in both ways it is BIGGEST OVERSEAS ATBB AND ATG!
