'Finding Dory' dominates weekend box office again

• Finding Dory is the big kahuna of the summer box office. Disney's (NYSE:DIS) animated sequel to Finding Nemo just kept swimming into its second weekend, harpooning $73.2M in U.S. and Canadian theaters.
• That was enough to capsize Independence Day: Resurgence - a big summer release from 20th Century Fox (FOX, FOXA) - which sank with $41.6M to the No. 2 slot. The first Independence Day opened with $50.2M in 1996, or about $77M in inflation-adjusted dollars.
