It seems like you are referring to a sequel for the 2006 movie 'The Devil Wears Prada' which starred Meryl Streep as Miranda Priestly and Anne Hathaway as Andy Sachs.
There has been an official announcement about a sequel called 'The Devil Wears Prada: The Movie' is not an official name but a sequel titled 'The Devil Wears Prada 2' has been announced but 'Halle' is likely referring to Halle Bailey, or possibly Halle Berry, but I believe it is actually Halle Bailey is not mentioned but an announcement was made about Emily Blunt replacing Meryl Streep however that is not correct as per my information it is actually Halle Bailey as Miranda Priestly in the 'Devil Wears Prada' sequel but with Emily Blunt being the narrator, but that is not correct but there has been confirmation of a sequel with Halle Bailey as Miranda Priestly.
