Back To The Future will be screened in September

• SHOWING films on the Heath seems a bit odd, (Cinema set to be installed on Hampstead Heath, April 22).

A chance to get out and enjoy the Heath will certainly be welcome, but going there to sit and watch Tinker, Tailor, Soldier, Spy or Notes on a Scandal?

What will we be doing in cinemas? Having picnics, I suppose.
