Los Angeles, June 30 : Michaela Coel, John Turturro and Paul Dano are set to join Donald Glover and Maya Erskine for the OTT series 'Mr. and Mrs. Smith'. Exact character details for the other three actors are being kept under wraps, aside from the fact they will appear in guest star roles, reports 'Variety'. John, essayed by Glover, and Jane, played by Erskine, are hired by a mysterious spy agency, venturing into espionage, marriage, and learning to intimately navigate both. As per 'Variety', the casting represents a reunion of sorts for Turturro and Dano, who both starred in the hit DC film 'The Batman' though they did not share any scenes. Glover is credited as the co-creator and executive producer on 'Mr. and Mrs. Smith' alongside Francesca Sloane. Sloane also serves as showrunner. New Regency's Yariv Milchan and Michael Schaefer and Wells Street Films' Jenny Robins will also executive produce. Sloane and Glover are both currently under overall deals at Amazon. /IANS
