Gangsta Granny

This David Walliams book adapted for TV showcases Julia McKenzie as a cabbage obsessed grandmother who also masquerades as an international jewel thief.

Her grandson Ben despairs of being sent to his dull grandmother's house every Friday night by his parents (played David Walliams and Miranda Hart) while they go ballroom dancing.

However Ben soon realises that his grandmother has hidden talents beyond cabbage soup and soon hatches a plan to steal the Crown Jewels whilst evading a nosey neighbour played by Rob Brydon.

It is a film that will be a hit with the kids although adults would be nonplussed until Joanna Lumley appears as the Queen and starts dancing.

It's a touching tale about bonding with the elderly but I really expected something more involving. Walliams and Hart provide able support but not enough laughs with their strictly dancing carry on.

Look out for Robbie Williams as Latino dancer Flavio.
