Theme of possible communication in Solaris and one or two other works.

Full Prompt: In Solaris, the three scientists strive to establish a meaningful communication with the alien intelligent life that is the ocean. It is unclear whether true communication, and understanding, will ever be possible. How is this theme of possible communication with an alien Other treated here and in one (or two) other works we have read or watched this semester?

Please use the films Arrival, directed by Denis Villenueve in 2016, and/or District 9, directed by Neill Blomkamp in 2009, as the other works.
