Did You Know?

Aside from playing the Seatopian Emperor Antonio, Robert Dunham, who was also a stuntman and vehicle racer, also played one of the two the "Unit 1" Seatopian Agents (he was the one on the motorcycle) in one of the car chase scenes (where he and another agent were chasing Yutaka Hayashi's character). The last shot where he gets splashed on with cement was done with another actor, because Dunham had to get to the studio that day to record his part, and didn't want to have to get cleaned up on the way.See more »

How can a film so shoddy be so much fun?, 19 April 2004
Author: DrLenera

Godzilla Vs Megalon is often regarded by Godzilla fans as the low point of the series. Indeed,in terms of conventional movie making,this is indeed a bad film. Stupid plot,zero characterisation,shoddy effects,awful music,you name it. There's even a brief bit where the actors stand still waiting for 'action'-obviously no one cared to edit this out. However,sometimes a bad film can be fun,and this is a case in point.

The film is so fast moving and action packed it's as if all the so-called 'dull'bits have been edited out. No slow build-up to the monsters here-the human part of the story is a constant series of vehicle chases,fights and kidnaps. The friendly flying robot Jet Jaguar has such a goofy charm that can't really dislike him,despite the shameless pandering to small kids,and Megalon and the previously seen Gigan really make a surreal pair of evil monsters. As with Godzilla Vs Gigan,the film is rife with footage from previous Godzilla films,but you have to almost admire the nerve in scenes like Megalon's attack on Tokyo,where all the exploding buildings are from the Ghidorah attack sequence in Ghidorah the Three Monster,the filmmakers almost getting away with it because Ghidorah's ray looks a bit like Megalon's. Oddly enough,the uncut version {many versions are badly cut} is surprisingly violent considering the target audience.

The phrase "so bad it's good"was made for this movie. Badly made in every way,and with no artistic merit whatsoever,but inspite of,or maybe even because of this,it's FUN!!!
