Seven years after The Invisible Man Appears, Daiei released this sequel which begins with a series of murders that seem to be the work of an invisible man. However, there seems to be the sound of buzzing with each kill.

It’s the work of a war criminal who created the formula and as a result, was left stranded on the island where his lab was. Now, he’s killing each of his associates in their new lives with the help of his brutal assistant, who is now addicted to the formula that allows him to become a human fly.

Now that scientists have made the invisible formula safe for humans, can a brave soul — or two — use it to protect the world from the Human Fly, who is now leaving bombs on trains and killing hundreds of people at a time?

At one point, this was going to be released in the U.S. as The Murdering Mite. It was never released, however.

How awesome is it that this movie basically has two Vincent Price characters, the Invisible Man and the Fly, fighting against one another? Seriously, the little fly man is super sinister and awesome in every scene, making this movie for me.

You can get this with The Invisible Man Appears on a new double blu ray from Arrow Video.
