I always found it funny that Nick Fury always gets to be the ur-example because I really don't remember any blowback to his casting as opposed to the Duncan casting. Also funny because Duncan ending up owning that movie and being the best thing about it and winning everyone over as the Kingpin.Race swapping works if the actor nails it so well the race swap is worth it. Sam Jackson's Nick Fury is the ur-example. Michael Clark Duncan's Kingpin, too.
