Foxx buried his own wounds to softly effect his character and leave us a record that is boundless. That show, that character only improves with the years. "Aunt Esther" being "Fred's" sister-in-law, "Elizabeth's" actual sister is a stunning achievement and a well thought out casting decision. She brings "Elizabeth" to life, makes her real. Makes us notice her then when Foxx cites her continually. We feel that loss, wonder what she was like, was she beautiful? We're they beautiful together at prime? What was "Lamont" like as a infant? It leads to many incredible moments as when Fred is harkening to "Elizabet," not so much in the heart attack act (because that is slap stick), but, in everything else that she is cited in, it's awesome.
