The latest British black comedy Keeping Mum, hit the big screen this week and was somewhat disappointing.

Despite casting a string of big names, such as Patrick Swayze, Rowan Atkinson, Maggie Smith and Kristin Scott Thomas the plot was simply a let down.

But despite its unrealistic story-line, it was undeniably comical in parts.

The film is about the life of a meek country vicar who is unaware his wife is having an affair, and that his family's housekeeper is not quite what she seems.

Walter Goodfellow (Atkinson) is an absent minded vicar blissfully unaware his wife Gloria (Scott Thomas) is planning her great escape with her golf instructor (Swayze).

He also turns a blind eye to the fact his teenage daughter, Holly (Tamsin Egerton) has a different boyfriend daily! And his son Petey is being bullied at school.

Of course all this changes when supernanny Grace (Smith) enters the Goodfellow household, complete with a mysterious trunk and a shady past.

At first glance it appears Grace has everything under control until Gloria discovers her shifty past.

Her desire to dispose of those who interfere with the Goodfellow family soon arouses suspicion and accidents need to be explained.

While Walter dedicates himself to writing a speech for a church convention he fails to notice the unusual goings-on in his own home.

This film is definitely worth a watch on a Sunday afternoon, if it is on the TV - but I wouldn't make a trip to the cinema especially to see it.
