Malcolm In The Middle Cast: Where Are They Now?
6. Erik Per Sullivan - Dewey
Erik Per Sullivan played Dewey, Malcolm's adorable and often underestimated younger brother.
He was only 11 in the first season of Malcolm in the Middle, and he proved time and again to be a brilliant actor.
However, once the show ended, Per Sullivan stopped acting almost entirely. He had a role in the 2010 movie Twelve, alongside Curtis "50 Cent" Jackson, and then he disappeared from Hollywood.
He keeps a low profile online and in real life, although he did contribute an afterword for children's book Together along with Malcolm in the Middle co-star Jane Kaczmarek.
Although he is now 28 years old, he still looks almost exactly the same as we remember him from his time as Dewey.
