I actually had a dream I went to see this last night. It was really odd and not what I expected. Danny McBride had a hollow concave section in the top of his head so that trays of snacks and drinks could be clicked into it, and he walked around the ship serving the other crew members biscuits. It was someone's birthday but I couldn't tell who. Then the action kicked off and he shrank to a few inches tall and had to evade a full sized alien in a living room, hopping over small obstacles and sometimes scaling the actual alien itself. It was all filmed side-on like a retro platform game.
I'm only sharing this on the very, very, very slim chance this is what the film turns out to be, so that when I swear I predicted it nobody can call me a liar.
It wasn't a great movie to be honest.
