Definitely a price error. Get it while you can. Generally the lowest it's gotten to is $49.99: https://www.cheapcharts.info/au/itunes/movies/776215550/Harr…
Note: You don't need an Apple TV subscription. If not using Apple/Mac, you can create an apple account and download the Apple TV app in Windows and purchase/watch the film. You could potentially download the Apple TV app on your Smart TV and purchase there too. Once purchased, you can watch on the Apple TV app on your Smart TV. The subscription is an additional feature for Apple TV - buying/renting films is separate. You cannot use Android to purchase/watch the films.
