Tim Roth, the actor best known to audiences as the bleeding Mr Orange in Reservoir Dogs, has established himself as a talented character actor, specialising in accents and villains. The thirtysomething Londoner first planned to study sculpture but ended up switching to acting and soon established his name on the stage and in TV movies. A move to Hollywood cemented his career as he became one of the new generation of fashionable British talents. In the 1993 fact-based mini-series Murder In The Heartland (Pearl, 12.55am), he portrays a horribly chilling Charles Starkweather, a teenager who in the winter of 1958 carried out a 44-hour killing spree that claimed 11 lives. The 19-year-old held the state of Nebraska almost hostage to his unprecedented reign of terror. The murders were touched upon in the fictionalised feature film Badlands and Bruce Springstein examined this dark chapter in United States history in his ballad Nebraska, but the story had never been told until this mini-series. Starkweather, accompanied by his 14-year-old girlfriend, Caril Ann Fugate (Fairuza Balk), was finally captured after a high-speed chase through the Badlands of Wyoming. Quickly tried and sentenced to the electric chair, his guilt was never questioned. But what, if anything, did the impressionable Caril have to do with the killings? The pair had fled after Caril's parents had forbidden her to see Charlie. Naively believing herself in love, she accompanied him on his marathon flight from the law. But her love soon turned to fear when she found out his first victims were her family and she could be next. A 1,200-man posse, backed by the National Guard, formed a dragnet for the teenagers. At last, Caril surrendered and was captured. Then a jury had to decide - was she Starkweather's willing accomplice or his tragic victim? John McArthur (Brian Dennehy), her lawyer, believed the former; prosecuting lawyer Elmer Scheele (Randy Quaid), who represented the families of the victims, was equally committed to seeing Caril receive the same death-row sentence as Starkweather. Their battle is at the heart of this gripping mini-series that has convincing performances all round and is worth staying up to watch. In tonight's The Fresh Prince Of Bel-Air (Pearl, 6.50pm), Will Smith, under the tutelage of television personality Dick Clark, shows how the series is produced backstage. Out-takes from the six seasons are featured as Smith interviews the stars in their dressing rooms. James Avery shows Smith his customised dressing room and Smith gets a cosmetic lesson in the hair and make-up room. Finally, Smith and Clark watch more out-takes, all of which are considerably more entertaining than the usual show. Jamie Lee Curtis is surprisingly convincing in the unusual role of predator in Mother's Boy (Pearl, 9.30pm), a thriller in the Hand That Rocks The Cradle vein. Curtis plays a mum, Jude, who returns to claim her boys after deserting the family. When her pleas for forgiveness fail, she tries to worm her way into the boys' hearts by instilling lies about their father's new girlfriend, Joanne Whalley-Kilmer. In the last look at sex and the silver screen in 100 Years Of Sex (World, 12.50am), the Legion of Decency re-emerges, AIDS enters the national vocabulary and the American Family Association declares a 'cultural war'.
