FishTank deleted Template:Infobox Film/Draft (which I didn't know existed) and that seemed to have fixed the issue (I'm assuming including whether or not there's an existing draft now is a factor in determining whether or not an infobox is a PI).

Edit: Looking further it looks like he created the draft and then deleted it as a null edit.
