HomePod plays Movie Soundtrack instead of Movie

How do I get Siri to play a movie instead of the movie soundtrack. HomePod is currently useless for playing movies on the AppleTV. If I ask it to “play Moana on the Big Screen”, it will instead play the soundtrack in Apple Music on the AppleTV instead of playing the movie. It’s a TELEVISION, why does it default to Apple Music?! So annoying! Even “Play the MOVIE Moana on the Big Screen” plays the soundtrack.
