1. Please note that this programme is not comparable to things likes 'Ghost-hunting with McFly' or whatever. By 'the professionals' they mean trained chefs, not The Professionals. So do not expect to see Bodie and Doyle battling it out in a restaurant kitchen. If that did happen presumably it will be called Celebrity Masterchef: The Professionals.
2. Greg Wallace has added another string to his bow in this series. In addition to being required to perform his traditional ' dessert gurn', he is also employed as a professional echo for Michel Roux Jnr.
