It looks like Paprika is back in play as the folks at Tubi have now added the film in its original Japanese language with English subtitles to their service here.
They originally added it in mid-to-late August but it wasn’t on there long before it was removed.
The 2006 feature film was directed by Satoshi Kon from a screenplay by Kon and Seishi Minakami based on the original story by Yasutaka Tsutsui.
