WITH a career spanning 25 years that has seen them top the charts and headline huge concerts around the world, the musical magic of Genesis will grace our screens tonight with Genesis: We Can't Dance (World, 9.30pm). This live recording was taken from their show at Hanover in July last year as part of their first world tour since 1987 during which the band were at their most popular. The concert features the balding rockers' biggest hits which include Mama, Land of Confusion and of course We Can't Dance. Thankfully Phil Collins, Mike Rutherford and Tony Banks have kept their own highly-successful solo material out of the set-list, concentrating on the classics that made Genesis one of the most progressive rock bands of the past two decades. LATE night thrills are on offer from World tonight with the airing of Trapped (1am, Original Running Time 100mins). The lights are out, the phones are dead, and a crazed killer is on a late-night rampage through a newly-built, high-tech office building and is after Marianne, played by Kathleen Quinlan. The usual cat-and-mouse games ensue, bodies are beaten with a baseball bat and carpets are stained with blood - great stuff, until the obligatory love interest comes into the plot in the form of an industrial spy, played by Bruce Abbott. This made-for-TV flick is surprisingly good in its ability to keep the suspense flowing but do not expect an original, thought stimulating plot. OH no! Not again. Police Academy 2: Their First Assignment (Pearl, 9.30pm. ORT 94 mins) has been on television so many times I think even my grandmother knows the script word for word. But, it can still provide a few laughs. The bumbling police cadets have just graduated from the academy and have been given their first assignment - to catch and lock-up a nutty motorcycle gang led by an unintelligible Zed, played by comedian Bobcat Goldthwait. The gang have led a riot in the streets and it is up to the cadets to clean up the mess. The usual Police Academy cast of Steve Guttenberg, Bubba Smith, David Graf and Michael Winslow star in this corny, but funny, fast film. A SLICE of the extraordinaryis on offer for night owls late this evening with the off-beat comedy Mystery Train (Pearl 12.05am. ORT 112 mins). A film with three separate stories along the same theme, it tells of the creepy escapades of a group of tourists who have come to Memphis. A Japanese couple (Masatoshi Nagase and Youki Kudoh) are Elvis fans and have come to visit the King's burial shrine, a widow (Nicoletta Braschi) is trying to fly the remains of her dead husband back to Italy and an English warehouse worker (Joe Strummer)is feeling suicidal after being retrenched from his job. All these stories intertwine in a mish-mash of hilarious and spooky happenings that cross cultures and emotions. WILDLIFE fans can tune into Pearl at 8.30pm for tonight's edition of Man's Heritage called Penguin Summer in the Falklands. This documentary looks at the Falkland Islands off the South American coast and how it is the summer holiday ground for millions of penguins and seals who flock to the islets from the chilly south Atlantic seas. The footage features superb scenery and photography and catches spectacular sights of surfing penguins and fighting elephant seals.
