Samantha Morton is opening up about losing her role in Spike Jonze’s 2013 sci-fi romance film, Her.

Morton — who is currently earning rave reviews for her role as the Greek sorceress Circe in Christopher Nolan’s The Odyssey — was originally the voice of Samantha, the AI operating system that Joaquin Phoenix’s Theodore Twombly falls in love with.

However, Samantha was recast in post-production, with Johansson taking over the role. The film went on to receive five Oscar nominations, including Best Picture, and won for Best Original Screenplay.

“I have to say that it’s every director’s prerogative in regard to the final cut of the film. For any job, you’re never guaranteed to be in it in the end. But with that, I was surprised. A little sad would be an understatement,” Morton told Josh Horowitz on his Happy Sad Confused podcast recently.

“The time I had on set with Joaquin [Phoenix], working with Spike on the script and finding Samantha, and all the work that we did was really special. We did some mad stuff,” the 49-year-old British actor continued.

“They designed and built a booth for me to record all my sound. I would be in this black, padded phone box, or I’d be in the trunk of a car. I think my version of Samantha was very different. She’s English,” she explained.

“Scarlett Johansson has a beautiful voice; she’s incredibly evocative. I got it, but I was sad. It does hurt when you’re fired from something. What I would have wished for was another chance in a booth to do an American accent. But Scarlett Johansson — I mean, come on.”

Morton is one of the many stars that make up the stellar cast of The Odyssey, which follows the Greek hero Odysseus (Matt Damon) as he spends more than 10 years trying to get back to Ithaca and his family after the Trojan War. Tom Holland, Robert Pattinson, Lupita Nyong’o, Zendaya and Charlize Theron also star.

Speaking ahead of the film’s July 17 release, Nolan claimed Morton received a reaction on set that he hasn’t seen since he directed the late Heath Ledger in 2008’s The Dark Knight.

“This was a massive film and [Circe] is someone who comes in and changes the dynamic,” Nolan told the Los Angeles Times.

“In some weird way, the film lived or died over that character. She was the fulcrum. I’ve always admired Samantha’s work, she brings so much depth of thinking about her role, there are no limitations on her performance.”

Nolan went on to recall that after one of Morton’s takes, “the crew gave her a round of applause.”

He said he discussed the moment with his wife and producing partner Emma Thomas, and that “she remembered that the last time that had happened was with Heath Ledger on The Dark Knight.”
