IN the middle of the Superman series mild-mannered actor Christopher Reeve removed his tights and underpants long enough to make The Aviator (Pearl, 9.30pm). It was released in 1985 but barely made it to cinemas because it was, well, not very good. Reeve realised the error of his ways and returned to Superman IV: The Quest For Peace, which came out in 1987. In The Aviator - directed by George Miller, but not the one of Mad Max fame - he plays a pioneer pilot in 1928, who crash lands in the middle of nowhere. His only passenger is whiny adolescent Rosanna Arquette, who soon after starred alongside whiny Madonna in Desperately Seeking Susan. What happens from here is the stuff of a 1,001 cliches. Reeve and Arquette initially detest each other. Then they realise that to survive they have to work together. Reeve fights off a bear. They fall in love. THE plot of The Purple Plain (World, 9.30pm) has much in common with that of The Aviator. This time Gregory Peck is the pilot and this time he crash-lands in the middle of the Burmese back-of-beyond and has to slash his way through the jungle to safety and a new set of values. The Purple Plain, already shown this year on World, is a 1954 British movie, based on the thriller by Eric Ambler. IT comes as no surprise that Eye To Eye With Connie Chung (Pearl, 8.30pm) deals with the O.J. Simpson case. This time it is reporter Bernard Goldberg, magnifying glass in hand, hacking his way through the evidence and the counter evidence, a job which has traditionally been left to judges, courts and juries. For the first time, reports Goldberg, we actually know how police came to suspect it may have been Simpson who killed Nicole Brown Simpson and her friend Ronald Goldman. After weeks of rumours and innuendo, Goldberg has the report that tells what the police found at Simpson's house the night of the murders. In a second report Goldberg is the pot calling the kettle black. He questions whether or not Simpson is likely to get a fair trial or not, particularly after all the leaks and conflicting media coverage. Celebrities have generally fared well in court in the past, it seems. When it looks bad for the defendant outside the courtroom, it can actually look good for him inside it. Meanwhile, Connie Chung slips into her deerstalker to examine DNA, otherwise known as the blueprint for life. DNA is becoming a critical element in criminal investigations. By one of those amazing coincidences that sees a Sunday follow a Saturday, DNA evidence will play a vital part in - and you are getting ahead of me here - the O.J. Simpson case. THE Highlander (World, 8.30pm) series is based on the film of the same name, but without its stars (Christopher Lambert and Sean Connery). This time Duncan McLeod is the pony-tailed immortal on an eternal journey to root out evil, ensure that good triumphs and go where no man has gone before. MORE of the usual goings-on in Thirtysomething (World, 1.00am), which is on its own eternal journey. Michael's idyllic unemployed existence is interrupted by a call from the boss of a big agency in California. Hope, however, gets offered work in Washington. IF you pay close attention to Moonlighting (STAR Plus, 9.30pm) you will see a phenomenon at work which is as strange and spectacular as the northern lights. Bruce Willis is without a doubt Bruce Willis, although younger, leaner and a little less wealthy. But something has happened to Cybill Shepherd. In close-up, her face is soft around the edges. What is the cameraman trying to hide? Surely Cybill is not human like the rest of us and getting older? In this evening's episode she fires David (Willis) after a lonely client is murdered by a potential bride.
