The posters portray matured members of the cast hidden behind large bouquets of flowers or pieces of furniture. Brook, who has taken over the part of Celia that was previously played by Jerry Hall, is the only one who is just 30.
In the posters, the actresses mimic the tongue-in-cheek humour of the 2003 film, posing nude but covering their modesty with household objects like large bouquets of flowers or pieces of furniture, reports guardian.co.uk.
Others in the cast include Janie Dee, Arabella Weir, Helen Lederer, Julie Goodyear, Hannah Waterman, Debbie Chazen, Jan Leeming and James Collier. It is being directed by Hamish McColl.
Brook is also celebrating as her boyfriend, England's rugby star Danny Cipriani, is returning to the pitch at Twickenham after injury.
