Alien Rom Com !?!

Excerpt from an interview from Benedict Wong's appearance on British Radio show: "Peter Serafionwicz Show" PS – is there a space ship in it/ BW – yeah PS – is there an alien in it/ BW – its a bit…y’know how you’ve got..so well its like an alien rom com of how the mum and dad met, and hes got a limp, and hes a ghost PS – well that sounds great BW – exclusive. What do we make of this? I can only surmise that he is referring to Michael Fassbender's character David, the robot (Dad) and the goo (Mum) that together create the xeno.
