ABC has seemingly made a move regarding their planned airing of a special airing of The Little Mermaid with live performances. The broadcast had been scheduled for October 3, but in announcing their season premiere dates, ABC's Tuesday comedies are scheduled to premiere in that slot.
It is unknown if the show has been canceled, delayed, or rescheduled at this point.
UPDATE (8/3/17): ABC has just released a statement about the special, announcing they're postponing it. The statement reads, “We are postponing the Little Mermaid Live! special. We love the idea of doing a live musical and want to make it wonderful. The project is so unique that we are making best efforts to do it next year and want to give it all the attention it deserves.”
The special was described as a two-hour special event where ABC will take Disney's The Little Mermaid animated feature film and intertwine it with show stopping live musical performances via cutting-edge technology for an explosive evening honoring one of Walt Disney’s most celebrated classics.
