There is something about Meryl Streep I find intensely irritating. There's no doubt she is a great actress but every time I start watching one of her films I fear I'll be wound up into a state of agitation simply through her intensity. No performance by Streep is light work: Sophie's Choice, The French Lieutenant's Woman, Plenty, A Cry In The Dark. Her earnestness is tangible and so much of the time it overwhelms the character portrayed. Streep remains true to form in Silkwood (Pearl, 1.50pm), the based-on-fact story of Karen Silkwood, who died in 1974 in a suspect car accident on her way to meet reporters with supposed evidence of safety violations at the plutonium factory where she worked. Full of her usual pregnant pauses, deep sighs and long looks, by the film's end I'm desperate to down a bottle of gin in an attempt to calm down. That said, it's a superb movie from Mike Nichols, who extracted sterling performances from Streep as a tough, hard-drinking woman, Kurt Russell as Silkwood's increasingly rejected live-in boyfriend, and an engagingly low-key Cher as a lesbian friend. It's also an excellent expose of the corruption of big business and what lengths people will go to stage a cover-up. The problem with well-documented true-to-life films is the ending is preordained and, for that reason alone, this 128-minute, slow-paced movie is simply too long to retain a tight grip to the end. That's something Rocky III (World, 9.30pm) never had to lose in the first place. While the formula for the first Rocky back in 1976 was entertaining in a primitive, innocent sort of way, this is simply primitive, inept and hollow. What's more, taking Mr T from the A-Team as Rocky's opponent was a cheap and tacky trick. Inevitably, as the series continued, it spiralled into more insipid nonsense and we undoubtedly have those later efforts to look forward to in the coming months. Turn instead tonight to the charismatic man-of-the-moment Nicolas Cage, another angst-ridden actor, who, while constantly pulling tremendous performances out of the hat, also manages to whisk me up in to an agitated state. Of course, there are additional reasons in his case. Shown on Cable Movies on Thursday night, Honeymoon In Vegas (Pearl, 9.30pm) is an amiable, if quickly forgettable comedy. Cage plays Jack Singer, a New York private detective, whose fear of commitment leads him in to all sorts of trouble when he loses his girlfriend (Sarah Jessica Parker) for the weekend to gambler Tommy (James Caan) during a poker game in Las Vegas. The film has its fair share of snappy one-liners and a goofy visual sense that fits the material. But Cage steals the show with his trademark blend of the sentimental and absurd. I shouldn't tell you, but the fabulous final scene has him returning to Vegas via parachute, wearing an illuminated Elvis costume. Wonderful, wonderful stuff that only Cage could pull off so spectacularly. Viva Las Vegas. And, if feel-good is what you want this grey, gloomy Easter, what better thing to do than stay up with the one you love and watch When Harry Met Sally (Pearl, 1.30am) for the 10th time - 'that scene' never fails to amuse.
