Jake Gyllenhaal has a box office winner on his hands. Not a blockbuster, though. Deadline is extrapolating that a weak Friday (Halloween) will deliver a $12-13 million weekend.

“Nightcrawler” has great reviews and will no doubt do better on a day and night that aren’t Halloween — it could clear $13 and get into the mid-teens, with a little luck and a big Saturday.

“Ouija” is falling off and — 47-50% down. A $10 million weekend. “Fury” is limping toward a $75-80 million payoff when all is said and done. Another $8 million this weekend.

“St. Vincent” is turning into an indie hit for Bill Murray. It will clear $20 million by midweek.

“The Book of Life” will be lucky to be in the low $40s by the time “Big Hero 6” opens and sucks all the animated box office dough away from it.
