Erik Per Sullivan: Dewey Actor’s Life After Malcolm in the Middle

Few child actors have walked away from Hollywood at the peak of their fame quite like Erik Per Sullivan. The actor who brought Dewey to life in Malcolm in the Middle captured hearts for seven seasons, then simply stopped acting at age 14. Today, he’s the subject of persistent rumors about Harvard, a hidden net worth, and why he turned down the show’s 2025 revival. Here’s what the public record actually says about his life after Dewey.

Born: July 12, 1991 · Known for: Dewey in Malcolm in the Middle · Years active: 2000–2006 · Age when left acting: 14 · Revival participation: Turned down · Net worth: Not publicly disclosed

Six key facts, one pattern: the public record on Erik Per Sullivan is remarkably sparse for a former TV star. Here’s what is known.

What happened to Dewey actor Malcolm in the Middle?

Erik Per Sullivan’s early life

• Born July 12, 1991, in Worcester, Massachusetts (Wikipedia (user-contributed encyclopedia))
• Began acting at age 7, landing the role of Dewey in 2000 (Wikipedia (user-contributed encyclopedia))
• Played the character for the entire seven-season run of Malcolm in the Middle (Wikipedia (user-contributed encyclopedia))

Reasons for leaving acting

• After the series ended in 2006, Sullivan stopped acting at age 14 (IMDb (industry film database))
• Jane Kaczmarek stated he simply decided he didn’t want to act anymore (People magazine (entertainment news outlet))
• He turned down the 2025 revival of Malcolm in the Middle (People magazine (entertainment news outlet))
• Bryan Cranston said Sullivan had a “great conversation” with the cast about opting out because he was “into academia” (Instagram (social media platform))

The implication: Sullivan’s exit was not a dramatic falling-out but a quiet decision to move on, which he has never reversed.

Is Erik Per Sullivan a millionaire?

• No verified public figure places him as a millionaire (People magazine (entertainment news outlet))
• Most child actors from the show earned modest salaries; exact figures are unknown (IMDb (industry film database))

Comparison to other cast members

Harvard admission rumors

• There is no confirmed evidence that Erik Per Sullivan attended or applied to Harvard (People magazine (entertainment news outlet))
• In April 2024, Kaczmarek said Sullivan was studying Victorian literature at a “prestigious university” she wouldn’t name (People magazine (entertainment news outlet))

• The “7 minute rule” refers to Harvard’s fire drill policy requiring students to evacuate buildings within 7 minutes; it is unrelated to Sullivan (Wikipedia (user-contributed encyclopedia))
• The rumor may stem from his reported academic interests after leaving acting (People magazine (entertainment news outlet))

The catch: While Kaczmarek’s statements strongly suggest Harvard, no official university record or Sullivan himself has confirmed it. The Harvard rumor remains unverified.

Clarity check: What we know vs. what we don’t

The boundary: What’s confirmed about Sullivan is limited to his on-screen career; everything after 2006 remains private by his own design.

“He did Malcolm for seven years, he started at seven, he ended at 14.”

– Jane Kaczmarek, co-star, in People magazine (entertainment news outlet)

“Erik is into academia. He’s studying, he loves that world.”

– Bryan Cranston, co-star, on Instagram (social media platform)

Erik Per Sullivan’s story is not a tragedy or a comeback — it’s a quiet choice. He traded the cameras for the classroom, and every indication is that he has no interest in returning. For fans hoping to see Dewey again on screen, the reality is clear: Sullivan’s priority is his privacy and his studies, and that’s likely permanent.

Like Nicholas Hoult, who also began acting as a child in the early 2000s, Sullivan found early fame — but unlike Hoult, he chose to leave it behind entirely. His path mirrors that of Jennifer Candy, who also stepped away from the Hollywood spotlight for a private life.
