We saw the movie “P.S.” (2004) last night, with the amazing and beautiful Laura Linney. She may be one of the most underrated actresses working today. She conveys such a huge amount of emotion, yet it’s never in your face; it’s always somewhat tightly contained within the physical space she inhabits, but you so get it! And this movie has one of the hottest little sex scenes I’ve yet seen (without any actual nakedness, even!). But neither Laura Linney’s performance nor the great little sex scenes are what I liked most about this movie.
