Here's some news set to spark "hysteria" among George O'Malley fans!

T.R. Knight — who played George for Grey's Anatomy's first five seasons — is now the male lead of a new Amazon drama pilot titled Hysteria, in which he'll co-star with Mena Suvari.

The prospective drama, as Deadline reports, "centers on Dr. Logan Harlow (Suvari), an exceptionally bright but socially awkward neurologist/psychiatrist … who travels to her hometown of Austin, Texas, to investigate a mysterious epidemic among high school girls that might be spreading through technology."

T.R. will play Logan's brother, Carter James Harlow, "a fiercely intense man who’s been on death row since he was 19 years old and is two months away from execution. [He] tries to convince his sister that the panic currently swallowing Austin is the same hysteria that sent him to prison 25 years ago, and if she will help to exonerate him, he’ll give her the clues she needs to resolve the crisis."

Since voluntarily leaving Grey's in 2009 — his character stepping in front of a bus to save a pedestrian — the 41-year-old actor has stuck mostly to the stage, starring in A Life in Theatre on Broadway in 2010 and Romeo and Juliet off-Broadway in 2013, among other theater roles.

On the screen, he appeared in 42 — alongside Grey's co-star James Pickens Jr. (Richard Webber) — and in a recurring role on The Good Wife.

He also married his partner, Patrick Leahy, in October.

Glad to hear that T.R. is doing so well for himself!
