It was last week when the reshoots on Deadpool 2 were confirmed via Josh Brolin amid rumors that the test screenings on the film had gone poorly.
It’s possible that the characters of Cable and/or Domino turned out really well and viewers just wanted to see more of them and less of Deadpool himself.
Of course, since we don’t have any details beyond rumors, it’s possible that the truth of the situation got a little lost in the translation.
Information was sketchy, and most was second hand, as test audiences are required to stay quiet about their experiences, but the prevailing rumor was that Deadpool 2 had some problems.
