[Dr. Sivana]

The movies on the link are public domain. So, Dr. Strangelove and The Third Man are out.

I would like to suggest a public domain B-movie that was unusually well done, and has, for my money, the nastiest (realistic) villainess I've seen. "Detour". Surprisingly good.

And gee, Ann Savage was such a pleasant leading-lady in little Columbia b-films. She goes over to PRC for “Detour” and becomes an all-out nightmare!

I remember showing “Detour” to a friend of mine in the early-1980s, and he was positively aghast at Savage and her character. Skin-crawling, disquieting. Nothing else remotely like it, from that era.
