I realise there is no incentive to simply reissue okder scenes in 1080 (or 4k if recorded in that) but really I would happily pay an extra ticket a scene to get the pick of the scenes I have bought in 720 in higher resolutions and I guess many others would too.
Seems a shame to look at some of the amazing scenes you have made and think they will never be available in anything above 720 (though we all know they were filmed in 1080 at least).
Come on, you could make a fair bit of money for old material this way because i bet a lot of people would happily pay a ticket per scene to have access to the best of the back catalogue in 1080!
