A Grey’s Anatomy star has been cast on Genius. T.R. Knight starred on Grey’s Anatomy for the first five seasons. He was one of the original interns on the drama. He will now take on the FBI.

Deadline reported that Knight will star on the National Geographic Channel series as J. Edgar Hoover. The news outlet revealed the following about his role:

“Knight will play J. Edgar Hoover, the first director of the FBI. He will play the driven and hard-charging political icon at different ages over multiple decades. Under Hoover’s direction, the Bureau amassed an enormous file on Einstein in an attempt to prove that he was a “subversive” and a secret communist. Hoover became focused on ruining Einstein, developing a personal vendetta against the famous scientist following incidents in which Hoover perceived that Einstein had humiliated the U.S. government.”

Genius will premiere in April. Will you check out this series? Tell us what you think.
