Dear Liar is two-actor play based on the letters of George Bernard Shaw and and Mrs. Patrick Campbell (the woman Shaw used as a model for Eliza Doolittle in Pygmalion). For decades Shaw and Campbell conducted a correspondence that this comedy highlights. Shaw, as the letters clear show, was in love with Campbell. Campbell admired Shaw, but she seems more interested in flirting than getting involved in what would have been a messy relationship.
Marsha Mason and Brian Cox are performing an online version of Dear Liar. If you’re interested, here’s the link to access the play: https://www.playbill.com/article/marsha-mason-and-brian-cox-star-in-dear-liar-virtual-reading-september-1
