questions about poetry allusion

Rating: Null/10 (16 December 2007)

It seemed to me that the movie made allusions to Dover Beach by Matthew Arnold. Does anyone else see that? Has Joe Wright said anything about it?
Especially the lines about the pebbles being thrown back on the beach by the waves, bringing the "eternal note of sadness in" and the last stanza, starting "Ah love, let us be true to one another for the world which seems to lie before us like a land of dreams so various, so beautiful, so new, has really neither joy, nor love, nor peace, nor certitude, nor help for pain, and we are here as on a darkling plain, swept by confused alarms of struggle and flight, where ignorant armies clash by night."
