It is a confronting reminder that you are growing older and time is swifly and irrevocably moving on when watching the trailer for the upcoming movie My Sister's Keeper and realising that Cameron Diaz is now playing the role of a matriarch, as oppossed to the perky, slightly naff singleton characters she has done for the past decade or so. This decision for Diaz to make the leap as an on-screen mother means she has crossed a fine line in her career. Never again can she play her trademark happy-go-lucky singleton charatcers. Rather, all her future parts will now be confined to the role as a mother, or if she plays a singleton she will have to do so with a tired, desperate my-biological-clock-is-ticking negataivity, a mini-genre that is already thoroughly covered on (and off) screen by Jennifer Aniston.
