Ek Tha Tiger has performed decently on third Monday as per sample reports received. ETT is sustaining well, though on lower end in its 3rd weekdays (20th day). ETT as per early estimate should collect around 1+ crore nett on 3rd Monday which is good, as 3rd Friday collected around 1.3 crore nett. So only a drop of 15-20% from 3rd Friday. Actual may vary a bit.
ETT 3rd week is heading for 10 crore nett, which is pretty decent as First and Second Week were excellent and above par respectively. ETT total box office collection is around 190 crore nett all India after 20 days. ETT has already crossed 3 Idiots distributor Share and thus become the biggest film with highest returns from theatres all India. Only question is whether ETT can touch or cross 3 Idiots lifetime collection figure. Going by general trend it looks highly difficult, but by Salman Box Office Trend, "Anything is Possible".
