Newcomers to the cast include Kevin Bishop and Nicholas Burns, who are taking over the roles of Carter and Tom, respectively, from Kris Marshall and Robert Webb. Bishop and Burns join holdovers Joanna Page and Ella Smith as Jeannie and Helen. Page will be replaced by Kelly Brook beginning Oct. 13.

The play revolves around the developing relationship of Tom (Burns) and the plus-sized Helen (Smith), much to the consternation of Tom's work colleagues Carter (Bishop) and Jeannie (Page), the latter of whom he has previously dated.

Burns has starred on television in "Benidorm," "Absolute Power," "Man Stroke Woman" and in the title role of "Nathan Barley." His London stage work includes The Madness of George Dubya and The Libertine.
