The 27-year-old, who first worked with Graham in 2012 series Good Cop, revealed she was considering softening her natural dialect in order to be “taken more seriously.”
Speaking to Tom Allen and Graham ahead of Virgin Media TV Bafta Awards, the Killing Eve actor said: “I always had this thing in my head that I needed to or that I would be taken more seriously if I did. And Stephen was like: ‘Are you kidding? Never, ever do that’.
“I was so glad that you reminded me because he is so authentic in himself. And to see someone from Liverpool doing what they are doing was so inspiring.”
Graham, 46, is nominated for Best Actor at tonight’s award ceremony, added he knew that Comer was talented from the very first time they worked together.
“Jodie had a small part, and she was just magnificent to work with,” he said. “I just saw her talent immediately. I said to her, look, I think you’ve got an amazing talent and I’d like to put you in touch with my agent on your behalf.”
Comer herself is up as Best Actress in tonight’s awards, having previously won the award at last year’s ceremony.
A number of stars were at the socially-distanced TV Bafta Awards, which took place behind closed doors and without an audience.
Normal People stars Paul Mescal and Daisy Edgar-Jones were among the celebrities at the event, the first time they had been reunited since the show first aired.
The pair were particularly keen to adhere to government guidelines, each holding one part of tape measure to ensure they were one metre apart
