Can anyone recommend a type of projection screen for movie viewing?Tripod?Ceiling mount? - tripod projection screens sent it back

I do it for a friend, because he want to use a white wall to project a screen on.I their films to make, but do not know what type.Should you get a tripod or one that bolts the roof and demolished? Portability would be a good thing, but it is difficult or cumbersome tripod? Is this the kind of laptops on the roof with less volume? All opinions please!
