My two bits worth on the original OP:
One of the problems with the C of E film is that, on account of its rather unusual subject matter, it hovers uneasily between being a conventional advert and being a state-sanctioned public information film of the sort you might have seen in cinemas during the war. For that reason, the whole enterprise feels slightly dishonest.
The phrase ‘Prayer is for everyone’ at the end is also used in a rather ‘sleight of hand’ way. Given that only the Lord’s Prayer is included, the covert message is ‘Our Prayer is for everyone’.
If the C of E sincerely wanted to promote prayer for all, I would like to have heard snatches of prayer from a variety of religions – and even better, I’d like to have heard people using their own words in prayer. A spread out network of people reciting a scripted ‘group prayer’ as portrayed in the film can feel oppressive if it’s not your group. For me, it rather brought to mind the enigmatic blonde children in the Village of the Damned who communicated telepathically and appeared to be plugged into the one hive mind.
The Lord’s Prayer is very familiar culturally in this country (the UK) so it might be easier to understand the potentially alienating effect on an outsider if the film is reimagined with each person saying a line from the Islamic equivalent, the Fatiha (unless of course you are Muslim and the Fatiha is comforting and familiar).
I actually feel there is an important more general message that could have been given as a gift from the C of E to the populace at large via the film –
Saying your hopes, fears and general musings out loud, whether in the form of prayer or otherwise, is for everyone
Now, that’s a take-home message that wouldn’t have me choking on my popcorn.
