Though a film filled with notable and hilarious gags, one of the best moments in Netflix and Sony Picture Animation's The Mitchells vs. the Machines is when a giant Furby comes to life. As you might imagine, given the title's implication, the movie deals with a family that is fighting electronics and robots across our great nation but the sequence with the Furbys (and other household appliances) is one of its best. Taking part in a behind-the-scenes tweet-along for the film, producer Christopher Miller revealed the lengths they went to to get the Furby in the movie, spoiler: a lot of letters.
