She is one of several suspects in the framing of her husband , who is a famous cartoon star accused of murder . She is voiced by Kathleen Turner , who was uncredited for her role . Amy Irving was cast to sing `` Why Do n't You Do Right ? '' ( a blues song made famous by Peggy Lee ) for Jessica 's first scene in the movie . According to animation director Richard Williams , other than being a beautiful female human toon temptress , she deeply loves her husband Roger . She even calls him her `` honey - bunny '' and `` darling . '' She claims that he makes her laugh , is a better lover than a driver and that he 's `` better than Goofy '' after Roger attempts to save her from Judge Doom and the Toon Patrol . As proof of her love , she tells Eddie that she 'll pay any price for Roger and she even helps prove him innocent by helping in the investigation . </P>
