"Mission: Impossible: Rogue Nation" (Paramount) showed initial strength with a $20.4 million combined Thursday night and Friday gross. The $150 million production is likely to show major international strength to boost it into profit, but these numbers are also strong. It is the best start for a Tom Cruise-starring film (adjusting ticket prices) since "M:I 3" in 2006, although with the caveat that "Ghost Protocol" in 2011 open in 425 IMAX theaters exclusively in 2011 its first weekend.
