Special Effects in Movies

[dontpanicbobby]

People of a certain age can remember enjoying black amd white movies. Well I'm watching "The Mysterious Doctor" (1943) and i can't help but marvel at the fog effects in this movie. Anyone know how they produced them. It couldn't have been dry ice. There are shots with thick fog in the background and just enough in the foreground to frame a perfect scene. No CGI in 1943 so how the heck did they do it?

It probably was dry ice they were using for fog effects actually. After all frozen CO2 is not exactly a new invention.

That's probably why they were using gas masks in the mine.
