Aamir Khan’s ‘Sitaare Zameen Par’ has grossed over Rs 90 crore in its first week, a significant achievement for a film relying on positive word-of-mouth. While initial earnings were strong, the film experienced a slight decline mid-week. The movie faces competition from new releases like Kajol’s ‘Maa’ and the South Indian film ‘Kannapa’, potentially impacting its future box office performance.
