Now that Christopher Nolan has effectively dashed Batman-fans' hopes of seeing any more favorite characters turn up in the "Dark Knight" universe; we're probably going to be seeing A LOT of fan-films popping up that mainly exist to imagine "Nolan-ized" versions of fan-filmmakers' favorite bad guys. Case in point: "Puppet Master" plays out as basically the first-act of a nonexistant "in-between-quel" centered around Riddler and The Ventriloquist. I dig it:
What I appreciate most about this is how plausible it is as an actual part of the series, warts and all - Edward Nygma as an obsessive FBI agent teaming up with "Mister Scarface" is a solid pitch, and everything from never calling either of them by their supervillain handles and giving Nygma's use of a cane an origin story absolutely nails the overly-expository "realism" of Nolan's Bat-films.
I would definitely rather watch the movie being suggested here than sit through TDKR again.
