Arrival (2016 Film)
Arrival (2016) can loosely be described as an alien movie- but a very unusual one! While the world may be at stake, the conflict at its heart is a linguistic one, as a linguist (Amy Adams) is tasked with deciphering the alien language. It is an interesting exploration of the idea that the language we speak shapes the way that we think (known as the Saphir Whorf hypothesis). Of course, it is still a Hollywood movie, not an academic text- see here for a discussion with a real life linguist about the plausibility of the ideas in the movie.
