After all the excitement surrounding it at the Toronto Film Festival, kidnapping drama Prisoners finally opened in first place at the box office this weekend with $21.4 million. Another newcomer, dance flick Battle Of The Year, took fifth place with $4.5 million. In between those two was last week's winner, Insidious: Chapter 2, which fell to second place with $14.2 million, bringing its cumulative earnings to $50.5 million. In third place, The Family only made $7 million its second week out — or half as much as its opening week — leaving its cumulative number at $25.6 million. Bilingual crossover Instructions Not Included, now in its fourth week, took fourth place with $5.7 million this weekend, which means it has now earned $34.2 million total.
