Mary Astor's Purple Diary: The Great American Sex Scandal of 1936 by Edward Sorel:
A year later, Little Women (1948) took a particularly heavy toll on her. She was in debt again, and not well physically or emotionally. As a result everything and everyone in that overproduced film put a strain on her. Young Elizabeth Taylor got engaged to Conrad Hilton Jr. and giggled on the phone while everyone waited on the set. June Allyson, who was assigned the role of sensitive and poetic Jo, chewed gum constantly and irritatingly. Worst of all was Peter Lawford’s inability to pronounce the word “porcupine” in take after take; it always came out as “porkypine.” The young cast found his endless flubs hilarious. Mary did not.
