Annie Potts, who portrays beloved character Meemaw on 'Young Sheldon', had one key request for her portrayal which she stuck to. Although Meemaw had faced rough encounters on the show 'The Big Bang Theory', she quickly became an adored character, requiring careful consideration when she was reprised in the prequel 'Young Sheldon'. Potts' casting elevated Meemaw's character, improving the viewing experience. One goal set for Potts was to establish an on-screen bond with Iain Armitage's Sheldon Cooper, ensuring that Meemaw was irrefutably his favorite family member. Guided by The Big Bang Theory's lore and Chuck Lorre's instructions, Potts added her unique touch on few unprescribed details. She advocated for a grey-haired appearance for her character as opposed to reflecting her on-screen daughter's color. Potts revealed feeling at ease playing Meemaw, drawing from women of similar background. According to Potts, breathing life to Meemaw was as simple as "putting on her bedroom slippers and going to work".
