New Delhi, July 7 -- Sitaare Zameen Par Box Office Collection Day 18: Aamir Khan's movie Sitaare Zameen Par saw a drastic fall in its earnings on Monday, Day 18, keeping the movie away from the prestigious Rs.150 crore mark for at least another day.

The movie had a significant hold on urban cities, but is now facing tough competition from Anurag Basu's Metro In Dino, which, too, focuses on the same target audience.

However, metro cities' potential is being hit by stiff competition from the Hollywood biggies-Jurassic World Rebirth and Brad Pitt's F1.

According to industry tracker Sacnilk, Sitaare Zameen Par earned a meagre Rs.70,00,000 till 6 PM on Monday, Day 18.

This means that the movie's total earnings remain below the Rs.150 crore...
