Shirley Valentine It is also a huge challenge for an actress. Not only did Pauline Collins make the role her own, both on the London stage and in the well-known film, but the demands of the part are considerable. The play is a good two hours long and, apart from the interval, Shirley is onstage all the time, telling the story of her life. In this KickstArt production, she is played by the versatile Lisa Bobbert who makes her a touching, salty and engaging character. And if the accent sometimes slips from Merseyside into Wales — well, it’s not too far away.
