Mia Farrow, who recently opened in the Broadway play 'The Roommate' alongside Patti LuPone, tested positive for COVID-19, leading to the cancellation of two performances. Marsha Mason, an associate director and veteran actor, stepped in to fill Farrow's role on September 15, performing with the script in hand. Mason expressed her excitement and gratitude for the opportunity, stating that it was exhilarating to perform with LuPone and to support her friend Farrow during her recovery. The play, directed by Jack O'Brien, officially opened on September 12 and will continue its run through December 15, with performances resuming shortly. While Carol Halstead is the designated understudy, the producers chose Mason for her experience and recognition. The incident highlights the ongoing impact of COVID-19 on live theater, as well as the adaptability of Broadway productions.
