The hostages are set to appear Thursday on "The Oprah Winfrey Show" two weeks after a gunman burst into the Discovery Communications building in Silver Spring, Md. Winfrey announced the interview on her website.
Police have said 43-year-old James Lee was shot dead by officers as his three captives were preparing to make a break for it.
The hostages included two Discovery employees and a security guard. Winfrey did not say whether all three would appear on her show.
This is Winfrey's final season for her show before she launches the Oprah Winfrey Network as a joint venture with Discovery.
