In House M.D., which actor played Dr. Remy “Thirteen” Hadley?

Olivia Wilde played Dr. Remy “Thirteen” Hadley in House M.D.

Thirteen is a physician who joins House’s diagnostic team during the fourth season. Her nickname comes from the numbered applicant identity she used during House’s selection process for new fellows. The character is a neurologist and becomes one of the show’s most prominent later team members.

The role gave Wilde a major television breakthrough before her later film career. Thirteen’s storylines include her diagnosis with Huntington’s disease and her complicated relationship with uncertainty, risk, and medical prognosis.

The character’s nickname is often treated as her primary name, but “Remy Hadley” is her canonical identity. She is also distinct from Amber Volakis, another applicant in the same selection storyline, and from Allison Cameron, a member of House’s original team.
