STAR WARS stars Harrison Ford, Carrie Fisher, Mark Hamill, R2-D2, and C-3P0 dominate the box office for the 30th week running. George Lucas’ $10 million gamble will go on to rake in $460 million. Two decades later, Ford will again play a heroic pilot (not to mention Commander-in-Chief) in Air Force One. ANIMAL DOCTOR and author James Herriot tops the nonfiction list with his third warm and fuzzy remembrance of All Things Wise and Wonderful. Herriot, whose 19 books would sell some 60 million copies, now has a library named after him in Glasgow. ON TV, ’50s fever scores ABC the top two shows with Happy Days and Laverne & Shirley. Garry Marshall, exec producer of both shows, would go on to direct the 1990 smash Pretty Woman. THE WORLD MOURNS Bing Crosby (left), beloved crooner (”White Christmas”) and Oscar winner (Going My Way), who died Oct. 14 of a heart attack at 73.
