Trailers for plays are generally a bit rubbish, aren't they? Film trailers give too much away and play trailers often tell you virtually nothing.

This trailer for the National Theatre Live screening of All My Sons at the Old Vic feels like a small step in the right direction - I wonder whether the fact that it will be shown alongside film trailers in cinemas to promote the event has focused attention on its purpose?

There is a hint of the story - family tension/marital tension - but if you know nothing about the play would it intrigue you enough to want to see it?

Or is the Old Vic and National Theatre Live relying on the star pull of Sally Field and Bill Pullman?

This is a play about truth, lies, love, loss and fatal decisions and you get little of that.

What do you think?
