DAIMAJIN (1966)

 If I didn't already know this was a giant monster flick before watching it and just happened to stumble across this movie playing somewhere I would think it was just another 60's samurai flick since that's really what it is up until about an hour in when our title character, who's a giant stone warrior statue, comes to life and starts smashing shit up.  This was still the 60's so these Japanese kaiju movies were still made seriously enough that you didn't instantly feel like a moron as soon as the movie started and by the time the monster action takes place it plays out like a revenge scene against an evil warlord character and his clan which is what usually happened in these type of films.  It's just that this time the revenge is super-sized.  A pretty unique entry in a usually pretty dumb genre and not exactly what I expected.
 There were two sequels to this which were all filmed at the same time to cut costs   and released a year apart.  I guess they were pretty confident that this was gonna be a popular movie with the Japanese people.  There's also a fairly recent TV series starring the stone-faced people-squisher.
