It may be that Deadline.com, after years of underestimating the Saturday impact of kids’ movies on weekend box office, is guessing right this time out.

“Interstellar,” almost 3 hours long and in limited IMAX release since Wed., won Friday with a healthy though not Marvel-sized $16.5 million take at the box office, on its way to a $50-52 million weekend. Very good.

“Big Hero 6,” opening Friday, with kids in school and late shows after kids’ bedtimes (well, good parents set earlier bedtimes) still did $16 million itself. It’s fanboy friendly and will pull the anime lovers out of the “Interstellar” set (they will see both, apparently).

So a big Saturday will give “Big Hero 6” and $55-60 million weekend, FTW.

Considering how weakly the box office has been performing this fall, that’s a welcome break.

Further down the charts, we see “St. Vincent” closing in on $30 million. Prediction, if it lingers into Dec. and closes in on $50, Bill Murray will get an Oscar nomination. A hit, even if it isn’t his greatest work, ups his chances. “Gone Girl” made lots of money, but has faded out of the top ten. Not sure if its Oscar chances fade with it, but that would be my guess.

“Fury” will finish in the $80 million range, “Nightcrawler” is still not pulling them in -a 44% drop, second week. Pity.
