So, I looked on my machine for an infection--there was none--and wondered where it came from. But this time I was paying better attention. It redirected to the following URL when I was just sitting there looking at an Al Pacino movie. Exact same site, exact same screen.
My guess is that IMDB is serving up a shady ad from whatever ad network they use.
Doing some digging, it doesn't seem like anyone else is reporting this issue. There's no way for me to say definitively that this came from IMDB--there's lots of ways to attack a computer--but it sure looks like it!
Malware scans come back clean and I haven't had any issues or anything suspicious with this Windows 10 / Chrome install. Uh, yeah, don't think I'll be clicking on this.

The admin contact for this domain seems to be a German encrypted email service. Searching the email shows this person, Chad Wessels is associated with over 100+ domains, most of which look shady to me. But there's more. The email search also links to a discussion forum post about phony Firefox updates, so it seems like good ole Chad has been quite busy.
I'm a software engineer but security really isn't my specialty, so I'm interested to see how this plays out and whatever people have run into this phony Chrome update.
