It’s a happy birthday to Brittany Snow, who turns 22 today, and perhaps celebrates by rocking this same, red bra-and-panties set, from John Tucker Must Die. Or maybe there’s new lingerie I don’t know about. At any rate, capitalizing on the Hairspray moment has thus far been tough for Snow, but she’ll be back onscreen in a few weeks in Prom Night (Sony/Screen Gems, April 11), even if that looks mostly like a blink-and-forget-it teen-money-grab affair. After that, the slate is even more iffy. Peter Tolan’s Finding Amanda, with Matthew Broderick and Peter Facinelli, at least sounds like it has the possibility of providing Snow new shadings, though the fact that it’s been hung up for so long after wrapping production doesn’t bode extremely well. An ensemble indie from Tony Kaye, Black Water Transit, has high intrigue value, but could just as easily disappear into the gaping void of one-week releases. I suppose, for right now at least, Snow’s firewall is the more commercial sounding The Vicious Kind, about a guy who falls for the girlfriend his brother brings home for Thanksgiving. Last fall’s Dan in Real Life played that narrative up to the tune of $47 million, so there’s obviously a bit of an audience, though a tweaking of that awful title will have to happen if the shopping mall set is to be at all wooed…
