Continuity mistake: When Grace sits on the sofa (before Jack enters) her black bag is on the table in front of her. When Jack enters, wearing the alien costume, the bag is suddenly on the floor. Then when Jack gets up to leave the bag has moved itself back onto the table. (00:22:20 - 00:23:40)
Revealing mistake: When Grace and Will are looking at the large tin of Protein shake powder, you can see there is tape covering all of the logos and brand name on the tin. (00:21:45)
