The cast of RSC’s modern-day adaptation of Romeo and Juliet included British-Asian actor Bally Gall as Romeo, and Scottish actor Karen Fishwick as Juliet.
Mercutio was portrayed by Charlotte Josephine as a woman.
After the Sunday Times listing was shared on social media, the RSC issued a statement saying it was “shocked and appalled” at the language used.
“[Writer] John Dugdale previewing Polly Findlay's 2018 RSC production of Macbeth, describes it as 'less garishly diverse in casting' than Erica Whyman's production of Romeo and Juliet the previous week,” the statement read.
“Such deliberate and offensive use of language demonstrates clear prejudice and devalues people, in this case specifically devaluing the work of RSC artists.”
The statement added that the RSC aims to reflect the diverse range of talent in the UK so its audiences “which we serve are all able to recognise themselves on stage”.
The Sunday Times has apologised for what it says was a production error, and removed the listing from its online edition.
In a statement, a Sunday Times spokesperson said: “We are sorry that an inappropriate reference appeared in our review of Macbeth. It has been removed from our online edition.”
