Theaters can’t release their attendance numbers without the knowledge of theater owners.

Now, the studios want to make sure they get it, according to sources familiar with the situation.

The industry is “deeply troubled” by the lack of transparency around the ratings process, said one person familiar with Warner Bros.’s deliberations.

The source declined to be named to discuss internal deliberations, saying they are not allowed to discuss personnel matters.

The industry source said the studio is “very concerned” about the lack in transparency around ratings. 

The sources said Warner Bros is “not happy” with the lack.

The source said Warner is “looking at all options” to make the ratings more transparent.

The sources declined to say what options were being considered, and Warner Bros has not responded to requests for comment. 

Warner Bros. Chairman Kevin Tsujihara told CNBC in an interview last month that the studio’s efforts to be transparent about the ratings could lead to an “adversarial environment” for studios, given the fact that “there are studios that are doing ratings like nobody’s business.”

 The studio is in the process of revamping the ratings, according the sources.

 “It’s a huge task.

We have a lot of work ahead of us,” the source said of revamp.
