So all the ice-skating pictures Natalie Portman on the set of her film Brothers are making more sense, now that we have the context of the trailer to go by.

Here’s a video preview of the thriller, which has A-listers Tobey Maguire, Jake Gyllenhaal and Natalie starring in a love triangle. It looks pretty good, with Tobey and Jake pitted against one another for the affection of sweet little Natalie. Lots of chemistry between Ms. Portman and Mr. Gyllenhaal.

Meanwhile, Natalie’s not yet in the mood to be promoting the flick, ducking the paparazzi during a visit to the Nobu Berkeley restaurant. But you can’t really blame the woman, since there’s not a red carpet in sight.
