Weekend actuals are in! is reporting that Shin Godzilla made $455,036 in North America over the weekend. BOM's erroneously lists it as playing in just 34 theaters on the whole weekend, for a wildly inaccurate per-theater average gross figure of over $13k, but 34 was just the Sunday theater number.
It played in 26 theaters on Friday and earned $52,133 for a per-theater average of $2,005.
It played in 311 theaters on Saturday and earned $327,679 for a per-theater average of $1,054.
It played in 34 theaters on Sunday and earned $75,224 for a per-theater average of $2,212.
(The nearest theaters to me were only playing it on Saturday at 1:30pm over the weekend.)
Shin Godzilla has made $1,501,390 in North America and it still has more showings today and tomorrow. Regarding Funimation releases, the $8m total of Dragon Ball Z: Resurrection F is out of reach but Shin Godzilla has already more than tripled the earnings of The Boy and the Beast or either of the Attack on Titan films.
