There can't be two more dissimilar films than the film we were supposed to see this evening, Rambo: First Blood II, and Impromptu (World, 9.32pm), which has replaced it. But for once we all have cause to be grateful for the swap. Impromptu is one of the most entertaining cinematic versions of the passion that flared between Polish composer Frederic Chopin and the butch author, George Sand. Judy Davis plays Sand, with all the uncompromising strength that makes her all performances so outstanding, and Hugh Grant exhibits precisely the right lack of backbone as Chopin. Both of them get plenty of acting support from Broadway star Bernadette Peters, Emma Thompson, and hammy Julian Sands rolling his eyes as usual. And not an automatic weapon, or MIA in sight. Ally McBeal (World, 8.30pm) has been all about how feeble Ally and Georgia are in enjoying their sexuality for weeks, with the wonderful shrink Tracy and Renee, not to mention Elaine the self-declared slut, demonstrating that girls really ought to have fun if they want to. This evening, Ally gets to take the moral high ground when Renee's behaviour, which in a man would be admirable, finally gets her in to a situation she cannot control. It is not a nice reversal, and shows just how impossible it is for modern single women to behave, which is probably the whole point. We also step a little deeper into creator David E Kelley's parallel universe when Fish's practice team up with Bobby Donnell's, he of The Practice, also written by Kelley. Given that Fish is only in the law business to pile up the cash, and Bobby spends most of his time trying not to think about it, we viewers know right from the outset this is going to be a troubled relationship. And it is, especially as the two sides have come together to defend a widow accused of axing her husband. She admits she has blackouts and agrees with the prosecution that she is the most likely suspect. And does Ally drool for Bobby? Well of course she does. That's what Ally always does instead of having sex. Ronnie had her US$20,000 encounter with an old high school sweetheart a couple of weeks ago, and has been much nicer since. Although it was hardly an earth-moving experience, at least it was an experience. It is partly because of this, and partly because of the fact his very-young girlfriend has dumped him for being too old, that she allows herself to be so nice to Bryce on the eve of the final signing of their divorce papers. But will he in turn be nice enough to persuade her not to sign them at all? A divorced or reunited Ronnie will transform Veronica's Closet (Pearl, 9pm) so this is a key episode. Do not forget to set the video while watching Ally salivate over Bobby on the other side.
