The film behind the announcement
Netflix's introduction credits Christopher Landon as writer and director of We Have a Ghost. David Harbour plays the ghost, Ernest, while Jahi Winston and Anthony Mackie are among the human cast; Jennifer Coolidge and Tig Notaro also appear. The film combines a family ghost story with the consequences of making the encounter famous online.
The title's first-person wording is a movie title, not a claim by NewsCubby that a haunting has been documented. Its premise should be understood as fictional entertainment rather than evidence about paranormal events.

Netflix's February 28, 2023 viewing report placed We Have a Ghost at the top of its English-language films list, reporting 40.47 million hours viewed for that reporting week. Hours viewed measure time spent watching, not the number of distinct people or paid signups. They also differ from box-office ticket revenue.
Mackie's role here is separate from Sam Wilson in Captain America. Following the actor across these films does not imply the characters share a fictional universe. The linked Marvel guide identifies the different project and role.
