Few actresses have looks that are as versatile as Holly Hunter's. She can be made to look impish or intense, grown-up or child-like, sweet or sultry, plain or pretty, simply by changing her hairstyle and costume. Hunter made an inauspicious start in movies with 1981's The Burning, a poor slasher film. She worked steadily throughout the 1980s but first attracted critical attention as Ed in Raising Arizona (1987). That same year, she won an Oscar nomination for her detailed portrayal of a workaholic in Broadcast News. In the 90s, she blossomed as an actress and her greatest success came in 1993 when she won the Best Actress award at the Cannes Film Festival and Best Actress Oscar for the repressed, mute immigrant woman in Jane Campion's smash The Piano. Once Around (World, 9.30pm) is an excellent vehicle for her acting talents, as well as those of Richard Dreyfuss, with whom she reteamed after playing together in Steven Spielberg's Always, though the script is not as consistent as the acting. Hunter plays a repressed Bostonian who meets her Mr Right, an amorous, but obnoxious salesman (Dreyfuss), who immediately alienates her family, creating a tug-of-love war. The see-saw script involves both romantic comedy and intense drama, and Swedish director Lasse Hallstrom (in his US directorial debut) infuses it with some real emotion. Laura San Giacomo, Roxanne Hart and Griffin Dunne co-star. In stark contrast to Hunter's chameleon-like versatility, Diane Keaton has achieved much of her success through one character (albeit in many incarnations), a clumsy eccentric full of the generation's neuroses and obsessions. Of course, the character owes a great deal to her former companion and mentor Woody Allen, whose many movies she has appeared in. Since that liaison, the character is not quite as prominent but it still pops up in many of her roles, including businesswoman JC Wiatt in Baby Boom (Pearl, 9.30pm). Wiatt is a driven New York businesswoman who is turned on by working late, corner offices and talking business in bed. Her life seems perfect until distant relatives die and leave their daughter, Elizabeth, in her care. It's a formula comedy but a tight scrip and Keaton's natural comic flair inject a good number of warming laughs into it. James Spader is thoroughly convincing as a predatory colleague wanting to move into her office space. Con artist Maggie (Lorraine Bracco) picks on the wrong man when she picks up Jack Shanks (Christopher Walken) in Scam (Pearl, 12.55am). Shanks is not the usual travelling businessman that she hustles, but an ex-FBI man with his own agenda involving millions in laundered underworld cash. He wants to recruit Maggie and her charms for a one-night con in Jamaica and he doesn't mind blackmailing her to do so. She'll get US$10,000 for her troubles, he gets a nylon travel pack of computer discs. When the scam goes inevitably sour, Jack and Maggie go on the run for their lives and, in true romance style, amour grows between the mismatched pair. Walken provides enough grit to give this film substance and director John Flynn provides some good atmosphere but it fails to live up to hopes. Rollercoaster (World, 2.40am) should be an exciting ride but bottoms out after an exciting opening. The sterling cast for such an average disaster-type movie includes Richard Widmark, Henry Fonda and a young Helen Hunt.
