Duplass attributes much of his and his brother's love for film to his appreciation for Raising Arizona.

In the second season of the show, Duplass's role became more prominent, and he was nominated for the Critics' Choice Television Award for Best Supporting Actor in a Comedy Series.

He was talking with director Joey Soloway at a dinner party about the difficulty they were having finding an actor to play what would end up being Duplass's role.
