Holiday
Starring Cary Grant, Katharine Hepburn
When Johnny Case falls in love with Julia, he is unaware that she comes from one of America's wealthiest families. Or that she has a drunken brother, a tyrannical father, plus an eccentric - and beautiful - sister. Romance, comedy and social satire are magnificently intertwined in this carefree film, which remains one of the great successes of Hollywood's golden years,

Pat and Mike
Starring Spencer Tracy, Katharine Hepburn
The screen's most enduring partnership - who regularly worked with George Cukor - are at their incomparable best in this romantic comedy. Spencer Tracy plays Mike Conovan, a sports promoter with some dubious 'business' friends, while Katharine Hepburn is the sportswoman he hopes to promote to America's lady champion. Complications develop - especially in the shape of Pat's boyfriend who puts her off her stroke in more ways than one.

The Schweppes Welsh Cup Final Bridgend v Cardiff from Cardiff Arms Park Bridgend, the Cup holders for the last two years, have reached this year's final without conceding a try. With backs like J. P. R. Williams Steve Fenwick , Gary Pearce and Gerald Williams , and British Lions forwards Ian Stephens and Gareth Williams , they form a formidable attacking unit. Cardiff beat last year's losing finalists Swansea in the semi-final, and look to outside-half Gareth Davies and captain John Scott to guide them to their first-ever Cup Final victory.

Resolution on Saturn. 1: The Rings
Travelling at more than ten times the speed of a rifle bullet, NASA's Voyager 1 spacecraft has flown Past the giant planet, Saturn, its moons and rings, and sent pictures back to Earth that are 10,000 times more detailed than any previous view. They show that Saturn's rings are 38,000 miles wide and less than a mile thick. Made of billions upon billions of independently orbiting chunks of ice, the rings turn out to be a unique fossil of the birth of our solar system. Like a young sun, surrounded by a disc of interstellar debris, Saturn has provided new evidence of the very mechanisms that led to the formation of our Earth 4 1/2 billion years ago.
