I actually am not sure whether Pepel (Пепел) is a series or a TV movie. It doesn’t seem to be a theatrical film, though. It’s supposed to air on October 27th (so about now) in Ukraine and on the 28th in Russia (through Channel 1). If my reading is okay, this seems to indicate that Pepel is a 12-episode series, and its got the whole historical war mystery setting.
The show stars Yevgeni Mironov, who also worked with Khamatova in Dostoevsky, as the title character, alongside Vladimir Mashkov, Elena Lyadova, and Sergei Garmash. I’m not sure who Khamatova is supposed to be playing.

I wonder if it will eventually get subtitled.
