Be wary of reports showing a queue outside the attraction, claiming it to be for the next show. IdF’s lobby capacity is smaller than that of the theater. SOP for Palais du Cinema is to close of the lobby once it’s full, then allow a line to gather outside. Once the first wave is allowed in, the rest are allowed in until the theater is filled (which is rare, although I’ve heard about it happening once).
I would presume the lobby is now even smaller with the art/cinema installation in it.
