Do you mean the classic Toho version for the 60's because the newer remakes "Godzilla against MechaGodzilla" is similar to Pacific Rim.
Cthulhu did appear onscreen in the Real Ghostbusters episode "The Collect Call of Cathulhu" [sic]. Which was nominally a kids' show, but wasn't really.
There's a little known Japanese movie called Yamato Takeru and the European movie Negadon to add to the list of live action kaiju, giant robot films.
Joe Haldeman is fairly pleased with the movie as it turned out. It had a great music score as well. Robot Wars, and another film were loose sequels to Robot Jox, but even these robot vs robot movies are uncommon Except in even lower grade B movies.
I meant all of them. I guess the newer ones use the robot as Pacific Rm does, but ultimately they are all Kaiju-vs Robot.
Watched it on the 4th of July. For an Asylum movie it wasn't that bad. Good for a low budget movie and I liked the design of the monsters.
Ok I managed to get through the movie but I ffwded a bit. My wife lasted 20 minutes. It was pretty awful in every way, the robot design: uninspired, the monsters: poor cgi. The acting was grade z. It is however, a perfectly legitimate live action kaiju-giant robot movie, albeit inspired by Pacific Rim.
