Hugh Grant plays her partner and manager St. Clair Bayfield. The film, directed by Stephen Frears is currently filming around London.
With the first official pic released already in May, it begs the question of whether they'll try to push this into cinemas by the end of the year. I still think it would fit perfectly in late summer 2016 as a comedy, but even some of the blogs I've been reading have inquired about the same thing. As usual, time will tell. Looking forward to this film regardless of when it's released.
