The Big Bang Theory star Melissa Rauch has been tapped for a guest starring role in Showtime's 1980s Wall Street comedy Black Monday. Rauch, best known for her role as Bernadette on the hit CBS comedy, will play Shira, the loving wife of trader Keith (Paul Scheer). 
After piloting the project (under its former titled Ball Street), Showtime has picked up 1980s Wall Street comedy Black Monday - starring Don Cheadle, Andrew Rannells and Regina Hall - to series with a ten episode order. Owing to the fact that Black Monday is set up as a co-pro with Sony Pictures Television, it is not immediately clear if it will be covered by Showtime's output deal with Sky or if SPT will be distributing it in the UK.
