Quite often clips like that are staged by the company itself to go viral on social media and get them brand awareness. There's something about the angle of the photography, the way that the CC opens the door fully, it all looks really staged to me. Nice creative work by Easyjet's marketing people. If this wasn't staged, I think the CC would have opened the door and peeked in, he wouldn't have opened it wide and invited everyone in the cabin to film (and why on earth would they be filming in the first place?). Also as has been noted, the space in the galley looks too big. One of the women clearly can't see what's happening but reacts as if she has seen everything, without asking what's going on.
