Caleb Ellsworth-Clark has played the role of Dewey in the Hulu revival of "Malcolm in the Middle," where he joins a returning cast including Frankie Muniz, Bryan Cranston, Jane Kaczmarek, Christopher Masterson and Justin Berfield. The role came with a significant responsibility as Dewey was closely associated with Erik Per Sullivan, who ultimately declined to return for the revival. Despite feeling nervous about his performance, Ellsson-Clark credits the returning cast with making him feel welcome at the set.
