Jul 13, 2020 At the top of the family tree is Harlan's wizened mother, Greatana Wanetta (K Callan), who doesn't say much, but sees a lot. Then there's Harlan. Throughout Knives Out, the mystery of who. May 06, 2020 Knives Out (2019) as a Wanetta “Great Nana” Thrombey; K Callan Television Series; Route 66 (1962) as a Western Union Operator; Great Performances (1972) as a Evelyn Jackson; One Day at a Time (1976-1977) as a Alice Butterfield; Barney Miller (1977) as a Gwen Baxter; Fish (1977) as a Mrs. Lester; All in the Family (1977) as a Veronica Cartwright. Get all the details on K Callan, watch interviews and videos, and see what else Bing knows.

Plot hole: The killer shows up at the scheduled appointment at 8 AM. They kill the idiot blackmailer with an overdose of morphine. Remember, that morphine that supposedly killed Thrombey in 10 minutes. Marta finds the blackmailer at 10 AM...alive, and does CPR on them, keeping them alive long enough for the ambulance to come and bring them to the hospital, even if in critical condition. So we went from 'kills in 10 minutes, you can't even try to save him' to 'after 2 hours, you are still hanging on'?(01:56:10)
