The Quatermass Xperiment

A number of decent performances and a gritty realistic view of London makes this little sci-fi spin-off still worth a look.

This forthright and watchable picture, with its terrific cast of veteran players such as Jack Warner, Thora Hird and the totemic Sam Kydd, is entirely happy in its own B-movie skin, with the “X” in “Xperiment” gleefully signalling its identity as a pulp shocker.

It's amazing how impressive Richard Wordsworth's performance remains.
