Why would't you have made it a pun on the Brothers Grimm?, 3:A - Whoopi had loved Star Trek since she saw the wonderful Nichelle Nichols playing Nyota Uhura in the original series. Katheryn Elizabeth Hudson is Katy Perry, and Olivia Jane Cockburn is Olivia Wilde, 4:C - Foxx told David Letterman in 2014 that he adopted a gender-neutral stage name because he had noticed that women tended to get called up on stage earlier in the night during stand-up open mics, 5:B - Her full name is Rachel Meghan Markle, but she's never elaborated on why she dropped the Rachel, 6:A - Born in 1972 he was given the name David Jude Heyworth Law.

Through his father, he is a nephew of the director, 11:A - He was born in Dulwich in 1887, 12:C - His family adopted the surname Phoenix to represent a new beginning after severing ties with the Children of God cult in the 1970s, 13:C - Her father Vasily Petrovich Mironoff had fled to England at the age of two, and changed the family name to Mirren in 1951, 14:B - Cruise was born Thomas Cruise Mapother IV in 1962, 15:C - The actor also used the stage name Michael Scott for a while before settling on Caine.
