The Millie/Tim hybrid is played by Alison Brie, but you can be forgiven if you don’t recognize her at all. In addition to extensive makeup work on set that saw parts of Dave Franco’s visage applied to the actresses, there were also visual effects employed that changed the shape of her face to be more like her co-star’s/husband’s. Shanks explained,

A lison Brie and husband Dave Franco have been together for over a decade, and they just seem to fall deeper in love every year. They also seem to become greater collaborators every year, releasing movie after movie that they either co-star, co-write, or co-produce.
