Either Keeley Hawes is going to be very busy or some of the rumors are not true. This one, however, has been found at two different sites.
Keeley Hawes is to join Marc Warren in BBC1 one-off comedy drama. Interestingly, it will be called Mutual Friends (not to be confused with Our Mutual Friend in which Keeley also starred!)
Warren will play Martin Grantham, who is married to Jen, played by Keeley Hawes. When
Martin’s best friend Carl throws himself under a train, it sets off a
disastrous sequence of events that change Martin’s life forever.
This is to be shown later this year.
