Any info about this movie??

Does anybody know like, anything about this movie besides what it's about and that it's being released in 2016? Tom Holland's one of my favorite actors and I've been waiting to see this but nothing new has come up about it in months. Of course it says it's being released in 2016 but there's been no trailer, plus that's also what imdb and everything else said about Lost City of Z, but that's not coming out until 2017 now. I heard somewhere that it was coming out in October but that doesn't make sense. It's also apparently been in post-production since December 2015. Can anybody tell me anything?
