No one suffered more magnificently in the early-talkie era than the inimitable Helen Twelvetrees. In Grand Parade, the actress is cast as Molly, the sweetheart of minstrel-show performer Jack Kelly. Rising to the top of his profession, Kelly plummets to the bottom thanks to his fondness for intoxicating beverages. Molly nurses and coddles Kelly back to health, giving nary a thought for her own comfort or happiness.
