PAVILION, SELSEY. Canadian star Robert Beatty becomes a work-shy Irishman who spends his time dreaming of a carefree life on a South Sea island in "ANOTHER SHORE," a comedy presented on Monday and Tuesday—but practical Moira Lister finally brings him back to earth, and Stanley Holloway helps too. On Wednesday, Ronald Colman and Greer Garson are co-starred in "RANDOM HARVEST." For sheer suspense, "CALL NORTHSIDE 777" is hard to beat. To be presented on Friday for two days, it tells the true story of a newspaper reporter's strange assignment to find evidence to free an innocent man from prison. James Stewart has the starring role.
