TVB Pearl has given tonight's movie slot over to SeaQuest DSV, the two-hour pilot of an expensive new underwater series executive produced by the king of Hollywood himself, Steven Spielberg. In fact, so enamoured was Spielberg of this submersible theme, he also opened a 'concept' restaurant in Los Angeles called Dive! with the man who spearheaded Disney's revival, Jeffrey Katzenberg. Of course Katzenberg left the Mighty Mouse, hooked up with Spielberg and David Geffen, and formed a brand new Hollywood studio - but that's another fishy story. It only goes to prove that Spielberg really, really likes submarines. But unfortunately American TV audiences haven't really returned that love, sinking SeaQuest DSV somewhere into the middle of the ratings. However, it's slickly-made, highly-watchable entertainment as you'll discover if you tune in at 9.30pm tonight. SeaQuest DSV is set in the year 2018 when the retired Captain Bridger (Roy Scheider) is coaxed back into naval service to helm the SeaQuest, a 300-metre military submarine that he designed himself. Bridger's remit is to patrol the underwater sea bed, which has now been colonised by people exploiting its rich natural resources. In future episodes of the series, he will trawl for piracy and environmental damage, but tonight's pilot show concerns the first SeaQuest commander, Captain Marilyn Stark (Stephanie Beacham), who turned out to be a bad hiring - mentally unstable, she was booted off the ship. Now she roams the seas as a submerged pirate, waiting to hijack her old command, the SeaQuest DSV, for nefarious purposes. With some good - and expensive - special effects, SeaQuest DSV will take to the perilous seas of TVB every Wednesday, starting this week at 8.30pm (fortunately relieving us of the dreadful Viper). BODY Bags (ATV World, 9.35pm) is a trilogy of tales a la New York Stories - only this time, they're horror stories. Perhaps this 1993 film is best compared to Tales from the Crypt. Only not quite as well received. Boasting a star-studded cast - from Star Wars ' Mark Hamill, to Stacy Keach, David Warner, Twiggy, Sheena Easton, Debbie Harry, Roger Corman and Robert Carradine and cameo performances from horrormeisters like Sam Raimi (The Evil Dead) and Wes Craven (A Nightmare on Elm Street) - Body Bags can be pretty gory. And when it's not being shocking, this film does tend to meander and lose the plot. But the cast and direction - by John Carpenter (Hallowe'en) and Tobe Hooper - is strong. Not as good as SeaQuest DSV, but passable entertainment all the same. PEOPLE Next Door (STAR Plus, 2am) is a horribly dated kitchen sink drama made in 1970 and starring Julie Harris, Eli Wallach and Cloris Leachman. With plenty of flares, sideburns and stripy tank tops, The People Next Door is about a husband and wife (Wallach and Leachman) who discover their daughter is a drug addict. Initially they blame their son, and try to force him out of the house in anger - but then they are made aware that the drug peddler who hooked their daughter is actually the A-grade student from the very smart family next door. Well, you never can tell, can you? Er, that seems to be the point of this picture, which David Greene directs with a distinct lack of innovation or style. Yet another oldie from STAR Plus, your cheap and cheerful 70s channel. MIND you, the Ruth Rendell Mysteries (STAR Plus, 9pm) are proving quite enjoyable, with the dashing Inspector Wexford pursuing the case of Angela Hathall in 'Shake Hands Forever'. Wexford is convinced he knows who the murderer is - and relentlessly pursues his hunch, isolating his wife Dora, Inspector Burden and all those around him. Is the inspector right? Or will the murderer get away with it? Spend the next two hours finding out.
