Warner Bros.’ “Argo” scored one of the best soph-sesh holds ever for a live-action film during a non-holiday period with just a 15.5% dip domestically, signaling perhaps one of this year’s best Stateside multiples based on opening weekend for a wide release.“Argo” launched Oct. 12-14 with $19 million; the film earned $16 million the following weekend. Pic’s cumed $47 million in North America through Oct. 24. The thriller’s drop ranks as one of the smallest for a film playing at more than 3,000 locations, behind such past hits as “Elf,” which fell 15.4% in its second frame, and “The Santa Clause 2,” which dipped 14.7%. Both of those pics targeted family auds and launched in early November. Warner expects “Argo” to continue legging out through the holiday period, and reckons an awards season push will boost B.O. At the time of the “Argo” opening, Warner domestic distribution chief Dan Fellman said he believed the film could reach $100 million domestically, which, based on the pic’s $19 million opening, would translate to a multiple of more than five times its bow. For context, Disney’s “The Odd Life of Timothy Green” cumed $50.6 million after debuting at $10.8 million — a five-times multiple — and Sony’s “Hope Springs” grossed more than four times its $14.7 million opening, with a Stateside cume of $63.5 million. Comparing “Argo” to helmer Ben Affleck’s 2010 pic “The Town” (both films launched around the same time), the latter film has a slight edge. “The Town” reached $53 million after 13 days domestically vs. “Argo’s” $47 million 13-day total. “Town” cumed $92 million Stateside.
