Presumably whoever is behind the advertisement felt that targeting this type of advert at a specific cinema audience (those wishing to watch Stars Wars) was a good business decision: bums on pews, so to speak.
Like everyone else I am regularly exposed to what are, for me, meaningless adverts - for instance for cat food (I don't have a cat, and never will) or face cream (I do have a face, but it is mostly hidden behind hair), so I just have to conclude that some people like cats or enjoy having creamy faces and simply ignore these encouragements. An advert for Christianity based on the Lord's Prayer is, for me, about as relevant as one claiming that Kattomeat is loved by felines.
When I go to the cinema I'd prefer just to see the film I've paid money to see but I recognise that advertising has always been part of the business model of cinemas - so I just take my iPod with me and listen to that until the seemingly interminable ads (all of them) are finished, since I'm not compelled to pay attention to any of them any more than I'm compelled to watch 'Songs of Praise' at home.
Personally I think this is probably a toe-curlingly cringe-laden attempt to make Christianity seem 'relevant' that is on a par with those cosmetic ads that tried to convince that without 'Bosewellox' female faces everywhere would be deprived of essential nutrients - I wouldn't ban it, but it might be best forgotten as being an embarrassingly twee idea in the first place: and one that can be easily ignored even if one has to sit through it.
