I used to think my answer was Wonka, but what JJP (Lawlor, really, as Eric would’ve done differently) did there was not at all impressive to me personally compared to what I felt was the potential of the theme - not to take away from the game’s fans, as I’m speaking solely of my own personal opinion here, and to each their own.
I think now my answer lines up with what some others here have said already: Matrix and/or Harry Potter.
