Actual links to actual sources would be nice, as it always is when making threads announcing things.
The Death Note movie has been ~in production~ for years now, the Attack on Titan one for a bit less as far as I can see. Anyway there's little substantial info on either of them.
Also making a single thread for two separate movies/series/whatever is usually not a good idea and
there's already a a thread for the SnK movie.
