Stephen Graham is no stranger to delivering unforgettable performances, but one of the most intriguing stories surrounding his BBC drama Time unfolded long before the cameras started rolling.

And remarkably, it involved a casting decision that initially left his own wife furious.

The acclaimed British actor, who played prison officer Eric McNally in Jimmy McGovern’s powerful three-part drama, revealed that his position as an executive producer allowed him to influence discussions about who might appear alongside him.

For Graham, it was an opportunity to recommend talented performers he believed could bring something special to the production.

But one particular suggestion proved far more personal than the others.

He put forward the name of Hannah Walters — his real-life wife — for the role of Sonia McNally, the wife of his character.

What might have seemed like a straightforward professional recommendation quickly became an awkward domestic situation.

Walters was far from delighted when she discovered what her husband had done.

Speaking during an appearance on Chris Moyles’ Radio X breakfast show, Graham explained how his expanded responsibilities gave him an unusual opportunity to participate in the casting process.

“This time, fortunately, I was involved in the respective – I was an executive producer. I’m sitting at the grown up’s table, you know what I mean?” he explained.

He revealed that director Lewis Arnold had been particularly receptive to his suggestions, which included actors Bobby Schofield and James Nelson-Joyce.

Then came the name that would create the biggest reaction.

Hannah Walters.

Graham recalled that Arnold was open to considering her, but the actress herself was initially uncomfortable with the idea.

Walters did not hide her frustration.

“I really told him off, really told him off,” she admitted during the interview.

“What are you doing! Why’ve you put my name in there? You shouldn’t have done that – that’s naughty!”

Her reaction highlighted an uncomfortable dilemma familiar to actors working alongside successful partners: the desire to be recognised for individual talent rather than personal connections.

But Graham’s recommendation was only the beginning.

What happened next would determine whether Walters actually secured the part.

Rather than simply receiving the role because of her husband’s involvement, Walters recorded an audition tape that was considered alongside submissions from other actresses.

And according to Graham, the final decision came down to her performance.

“Then she put herself on tape and obviously with all the other actresses that had put themselves on tape, he picked her because she was the best for the role,” he explained.

It was a crucial distinction.

Graham may have opened the door, but Arnold ultimately chose Walters on the strength of her audition.

There was no need for the couple’s marriage to become a substitute for professional judgment.

Instead, their existing relationship offered something particularly valuable to the story: an authentic connection between two characters whose marriage is placed under extraordinary emotional strain.

In Time, Eric McNally faces difficult moral decisions while navigating the dangerous realities of working inside a prison.

His relationship with Sonia adds a deeply human dimension to a drama already filled with guilt, fear and impossible choices.

And for Graham and Walters, portraying that relationship came with one rather obvious advantage.

“Because fortunately we had quite good chemistry,” Walters joked.

“It would have been shocking if he’d gone, ‘I’m sorry, it’s just not working between you.'”

Her light-hearted remark revealed the irony of the entire situation.

A suggestion that initially caused tension at home ultimately allowed the married couple to bring their natural chemistry to one of British television’s most emotionally demanding dramas.

Yet the most revealing aspect of Graham’s account was not that he recommended his wife.

It was that Arnold still required her to prove herself.

Although Graham did not disclose any mysterious last-minute discovery or secret intervention before a contract was signed, his account makes clear that Walters’ audition was the decisive factor.

And that is what makes the story so compelling.

Behind a seemingly risky casting suggestion was a genuine professional test — one that transformed an uncomfortable conversation between husband and wife into a memorable on-screen partnership.

For Walters, the experience ended very differently from how it began.

After initially reprimanding Graham for putting her name forward, she admitted she eventually felt grateful.

And for viewers watching Eric and Sonia McNally navigate the emotional turmoil of Time, the result was a relationship grounded in something that no casting director can manufacture: years of real-life familiarity, trust and understanding.
