What you see in the 2nd screenshot is the playlist – apparently you named it exactly like the movie… but it’s still a playlist.
You can add a description to it and it can have tons of other movies added to it. Once you add more videos, the poster will automatically update to show a collage of 4 random posters from the playlist.
But it won’t display the details of every single movie it contains (I imagine that’ll be quite a long list of actors if it was to show all of the actors from all the movies in the playlist).
There’s a feature suggestion to allow opening the individual movie pre-play screens (1st picture) of the items in a playlist. Currently you cannot do that.
