IT is hard to believe, but Back To The Future (World, 9.30pm) is nine years old. Its star, Michael J. Fox, has the appearance of being about the same age. He was not a teenager when he made this, but still manages to look like one. He plays Marty McFly, a decent lad-next-door who plays an electric guitar, sails about on his skateboard and courts pretty Jennifer Parker (Claudia Wells).
But all is not well in Marty's America. His father (Crispin Glover) is a wimp, his mother (Lea Thompson) is an alcoholic and his brother and sister are decidedly weird.
Marty's one true friend, apart from his girl, is the positively manic Dr Emmett Brown (a great performance from Christopher Lloyd) who has for some years been quietly working on a machine for time travel.
Marty accidently activates the device and finds himself back in 1955, where he encounters his own parents as teenagers. If that isn't troublesome enough, he also discovers that he doesn't have enough special plutonium fuel to return to his own time.
All this makes for a snappy, happy and wonderfully nostalgic outing, with ample time-travelling twists and a plethora of verbal and visual jokes. The acting is excellent from everyone. Back To The Future is one of the best family films of recent years. It gets off to an uncertain start but turns into frenetic, non-stop fun.
IF you want something frenetic but closer to home, The Tigers (Pearl, 9.30pm) looks at corruption in the Hong Kong Police force. It stars Andy Lau and Tony Leung and is the usual Hong Kong mish-mash of wooden acting, sensationalism and tomato ketchup.
The film focuses on a group of five policemen who accept a bribe (''black money'') from a crazed gangster (Tong Chen). Each man has a different reason for taking the pay-off, but - and do I smell a moral here? - they find their naughtiness destroys their friendships, their careers and in some cases their lives.
