I watched the MST3K treatment of this movie a couple of weeks ago. Talk about a tedious movie! I admire the fortitude it must have taked to watch it without the benefit of Mike and the Bots' riffing.
At first I was "WTF?
", because I didn't remember seeing "The Bat People" on any episode list. Then I remembered that Wikipedia
can be your friend. As shown on MST3K, the movie was titled "It Lives by Night
" and was episode #1010. I haven't gotten around to watching it yet, although I do intend to watch every episode some day (and yes, I do have all of them).
