It’s that rare beast: a rollicking action film with a subversive political agenda.

One of its decade’s more durable techno-thrillers.

John Badham's perpetually timely thriller boasts a match made in heaven of practical effects and miniature photography, building to one of the best action finales of the 1980s.

It has excellent production value, a fine performance from the great Roy Scheider, and the action sequences do provide some thrills, but in the end, you'll probably find yourself wishing that there was a little more to its plot.
