Ayan Mukerji's War 2 may have slowed down after its thunderous start, but it has still managed to cross the Rs 300 crore mark worldwide in its first week. The spy action drama, headlined by Hrithik Roshan and Jr NTR, faced a midweek slump, raising questions about how long it can sustain its box office run. Despite its big opening, the film's lifetime collections may fall short of what the makers had envisioned. On Wednesday, which marked day seven of release, the film collected just Rs 5.50 crore net in India, the lowest single-day figure so far.
