Wow, MiddleAged. You seem to have quite a memory! I, too, have been following Andrea's career since the beginning and can't remember a single interview in which she badmouthed another performer...especially Brooke Shields and Tatum O'Neal.
As for the Jackie Cooper (not Coogan)book, it is important to consider the source. Cooper's abrasiveness was legendary in Hollywood and his frequent personality conflicts eventually Cled to his removal as MASH television director.
