Yep, it's black & white and low budget but the film has great ideas and is executed incredibly well for the small amount of money they had to work with. The score by Bert Shefter and Paul Sawtell is probably the best the duo ever wrote. In fact, the title theme was so good it was re-worked for IT, THE TERROR FROM OUTER SPACE. Some people have said they think that cartoon animation was used for walking shots of KRONOS. I think it is stop-motion model animation, especially since Gene Warren is one of those credited for special effects and stop-motion was his specialty. Regardless of how it was achieved, KRONOS is about as much fun as they get. The special effects, while dated-looking now were as good as anything else you would see at the time it was released. I love this film which fortunately, has been preserved on an excellent widescreen DVD. The film has an enduring quality about it and never ceases to entertain me no matter how many times I see it. If you just like to have a plain old good time watching a movie, then I highly recommend KRONOS.
