It's true that release dates matter, even for major blockbusters, and I suspect The Secret Life of Pets 2 would've done better in a world without Toy Story 4 opening in the same month. How much better would Toy Story 4 have done if it opened over last weekend for Father's Day? It would've obviously crushed Men in Black International, assuming MIB stuck with its release date, but otherwise I wonder how many millions we're talking.
