The two Oscar winners, who married in 2003, released a statement through their publicists stating that they are both saddened by the development but that
"The split is entirely amicable and is by mutual agreement. Both parties are fully committed to the future joint parenting of their children."Local celebrity columnist Paul Robins writes for 'The Diary' that the partnership hit the rocks on the set of Revolutionary Road in which Mendes directed a series of 'steamy' sex scenes involving Winslet.
He notes that the subject matter of the film 'may have tempted fate' since it was also about a disintegrating marriage. And Geoffrey MacNabb investigates whether the stresses of the production process is likely to cause a rupture.
But perhaps it wasn't so much as case of life mirroring art as a master of his craft dictating the course of events. With rumours circulating that Mendes may have already begun an affair with Frost/Nixon star Rebbeca Hall did he have an ulterior motive in choosing this project?
An alternative undercurrent has also emerged with suggestions that the couple 'grew apart'. However this appears code for differences of opinion regarding career choices.
Following her split from the renowned master impresario Winslet is reportedly consoling herself in retreat in Mexico and may be considering a reconciliation with first husband, the more politically-minded independent producer/director, James Threapleton.
Interestingly for such a story with far-reaching name recognition it is only mainstream commercial publications which have covered it - nary a blogger has bothered to write a comment.
Does this indicate the true level of interest in celebrity gossip?
