Scarlett Johansson shows off her secret alien lair on the latest trailer for Under The Skin, and it looks like a pool. Which, OK — we did not see that coming.

Based on the novel by Michael Faber, Under The Skin is channeling the whole arty alien vibe, hard. But luckily, it seems to have the positive critical reviews to back it up.

In case you missed it, here's also the teaser that came out a while ago:

Under the Skin will be released in Los Angeles and New York on April 4th.
