SUNDAY-NIGHT blues were sure to have set in tonight following Love Story (Pearl, 2 pm), the original boy-meets-girl weepie, but for The X-Files (Pearl, 9.30 pm) with three episodes in one long supernatural-fest, including the first two instalments of the long-awaited third series. Sting (left), who will be performing here next week, discusses 15 years in the music industry in Speakeasy (Today, Channel V, 10.30 pm). The great Peter Cushing stars as a inventor with that regular of 1970s fantasy-adventure films, Doug McClure, in At The Earth's Core (Monday, World, 9.30 pm). Despite special effects which may be primitive by today's standards, it's an enjoyable, innocent screen-filler. Michelle Pfeiffer (left) puts in a decent performance as a gangster's moll trying to escape the Mafia in Married To The Mob (Pearl, Tuesday, 9.30 pm). Rutger Hauer (left) for once leaves his roles as menacing psychotic killers in Blind Fury (Wednesday, Pearl, 9.30 pm), playing a blind Vietnam veteran who takes on a drug dealer. The film is an American version of the 1960s samurai series featuring Zatoichi, the blind swordsman. Rik Mayall is type-cast as a scatological trouble-maker in Drop Dead Fred (Thursday, World, 9.30 pm), a crass, puerile tale about an imaginary childhood friend who comes back to wreck Phoebe Cates' life. Caesar And Cleopatra (Thursday, World, 12.55 pm) is notable only because director Gabriel Pascal took sand to location sets in Egypt to get the right colour. Invasion Of The Body Snatchers (Friday, World, 9.30 pm) is a remake of the 1956 science fiction classic, with small-town residents being duplicated and then replaced by aliens. Meg Ryan's (bottom left) fake-orgasm scene in Katz's Deli during When Harry Met Sally (Friday, Pearl, 1.30 am) has become a cinematic legend, but the film has plenty more to offer and it defined a genre of wry, bittersweet, comic love stories. If Not For You (Friday, Pearl, 6 pm) is a new comedy about two people who fall in love at first sight but are both engaged to marry someone else. Robert Duvall received an Oscar for his portrayal of a country singer who rediscovers the joys of life when he meets widow Tess Harper in Tender Mercies (Friday, World, 2.40 am). Incidentally, Duvall wrote his own songs. There was a lot of hype about The Day After (Saturday, Pearl, 12.20 am) and much of it was justified as it is a stark, chilling piece on the after-effects of a nuclear bomb.
