Phil Lord and Christopher Miller, the writing/directed duo behind The Lego Movie, faced a disappointing interim between projects when they left their positions as directors of Solo: A Star Wars Story in 2017. During this unfortunate fiasco, a soon-to-be-successful animated feature developed from a story by Lord was years into production. In 2018, Spider-Man: Into the Spider-Verse became the most critically acclaimed film this team had co-produced.
