The second weekend October record actually belongs to Alfonso Cuaron’s Gravity, at $43.1 million.
Interestingly, $42.5 won’t be a second weekend October record if that’s where Joker ends up.
For the record, Venom brought in $35 million in its second weekend.
That was a 56% drop for that movie, which is exactly the same percentage drop Joker will receive if it brings in the $42.5 million that Deadline is projecting.
