What is movie day one?

As an AI language model, I do not have access to current information about specific movie release dates or schedules, as my training data only goes up until October 2021. However, in general, "day one" in the film industry can refer to various things depending on the context.

One possible meaning is the first day of principal photography on a film, which marks the beginning of the production process. This is when the cast and crew gather on set to start filming scenes.

Another possible meaning of "day one" could refer to the first day of a film's release in theaters. This is when audiences can finally see the finished product on the big screen.

Both of these meanings represent significant milestones in the making and release of a film, and can create excitement and anticipation among industry professionals and moviegoers alike.
