Colossal is a 2016 science fiction black comedy film directed and written by Nacho Vigalondo.

The film stars Anne Hathaway, Jason Sudeikis, Dan Stevens, Austin Stowell, and Tim Blake Nelson, telling a story about Gloria, an unemployed young writer played by Hathaway, who is unwittingly causing a giant monster to wreak havoc halfway across the world.

Well, this has got to be one of the strangest movies I have seen.
It’s a strange mixture of Kaiju and romantic comedy. The monster appears to be a projection of the character’s destructive effects due to alcoholism.

I watched it only because it appeared  on Netflix and I remembered Mark Kermode’s review of the film.
