Vernon and Greg Tiernan co-directed the adult animated comedy Sausage Party (2016), from a story by Seth Rogen, Evan Goldberg, and Jonah Hill, as well as providing some of the voices. Vernon next co-produced and co-directed, again with Tiernan, an animated version of The Addams Family, which was released in October 2019. He supplied voice roles for both Sausage Party and The Addams Family, including Lurch in the latter. He was scheduled to return as director alongside Tiernan for The Addams Family 2, released in October 2021. In October 2020, it was announced that he would no longer be involved as director, though he ultimately received co-billing with Tiernan.
