Liev Schreiber, known for his role in “Ray Donovan,” was hospitalized on Sunday after experiencing a severe headache.

The actor, formerly linked to Naomi Watts, remained in the hospital overnight following doctors’ advice and underwent extensive testing on Monday, as reported by TMZ.

According to the site, the 58-year-old actor, based in New York, was mobile during his hospital stay. The exact cause of Schreiber’s headache has not yet been determined.

The Daily Mail has reached out to his representative for further information.

Schreiber gained fame with his performance in the 1996 film “Scream.” His recent projects include “The Perfect Couple” and “Caught Stealing.”

Originally from San Francisco, Schreiber is married to Taylor Neisen. The couple, who started dating in 2017, tied the knot in July 2023 and welcomed their first child, a daughter named Hazel Bee, in August 2023.

He also shares son Sasha, 17, and daughter Kai, 16 — who came out as transgender earlier this year — with his ex Naomi, 57. 

It’s not the first time the actor has had a health scare related to a headache.

In 2024, he revealed that he was diagnosed with a rare condition called transient global amnesia while starring in ‘Doubt: A Parable’ on Broadway.

‘The worst nightmare that an actor could possibly ever experience. I was in my dressing room and I had a terrible headache. I thought it was maybe a fast-food headache, but it felt a little stronger than that,’ he shared during an appearance on Late Night with Seth Meyers. 

Schreiber recently revealed why he became an actor in an interview with Italian publication IO Donna.

He said: ‘As a child, I was fascinated by clowns and enjoyed entertaining my family. My mother was a bit of a hippie; she placed more importance on art than money: she was a taxi driver, and as soon as she had some, she’d spend it on taking us to the movies or the theatre.’ 

Liev insisted his grandfather Alex – who emigrated to America from Ukraine and played the cello – was more of an influence and inspiration for him to go into acting than his dad, Tell Schreiber, who was an actor and theatre director. 

When asked what influence Tell had on him, Liev said: ‘Perhaps I was more inspired by the circus, where my grandfather took me. ‘At the exit, they sold little swords for children, and I remember playing with them in front of Madison Square Garden, thinking about The Legend of Robin Hood with Errol Flynn. 

‘My parents separated when I was four, and I grew up mostly with my mother, who was a bit of a hippie socialist who even lived in squats; artistic education was more important than anything else. We went to a movie theatre on Eighth Street where they showed old black-and-white films, but I think I appreciated them more as I grew older.’

Schreiber – who has vivid memories of watching films starring Charlie Chaplin and the Marx Brothers with his mother – is dad to daughter Hazel, his child with wife Taylor Neisen. 

The star is enjoying being a father in his 50s and says children give you a solid grounding when you work in Hollywood. 

The Hollywood actor – who has two teenage children from his relationship with actress Watts – said: ‘I could have had a more relaxed life, but with a small child, you have to provide stability, respect sleep and meal times. Children keep you grounded. 

‘When I had my first two, who are now 17 and 18, it was a strange time: my ex and I were the center of attention, and success can make you lose your sense of reality. Children bring you back to what’s truly important.’
