A big budget movie probably can’t experience the same kind of effect that Chick-fil-a can, but Chick-fil-a definitely benefited economically from its owners being homophobic. The fact is that the majority of the population does not go for fast food on any given day, and those that do have myriad choices. A relatively small portion of the population consciously choosing to go there instead of anywhere else, and to go there a little more than they would have otherwise, will make up for a much larger portion of the population choosing not to go there at all. The supporters will lose interest over time, but so will the boycotters (who will lose interest in proportion to how much they liked to go there before - there will only be a tiny number of people who went there a lot before and then stop altogether forever).
