So how much of a role did Jodie Foster have in getting a then-largely undiscovered Kristen Stewart her part in “The Yellow Handkerchief?”

Producer Arthur Cohn told journalists that Foster “urged” him to sign the pre-”Twilight” Stewart for the movie which only just opened in theaters on Friday.

“Nobody wanted me to take (Stewart) in the part of Martine, she was practically an unknown,” Cohn told the press at “The Yellow Handkerchief’s” press day. “But Jodie Foster, a close friend, urged me to take her.”

“So I took her.”

He repeated the same thoughts in the film’s official press notes which state that Foster “recommended” Stewart for the part. “I followed Jodie’s advice because she’s a great actress and director,” Cohn is quoted as saying in the notes.

Indeed Cohn and Foster are friends. And Foster and Stewart have had a mutual admiration thing going since Foster played the mother to the child actress in “The Panic Room.”

But when questioned about the Foster connection for “Handkerchief’s” casting, Stewart told journalists it was the first she had heard of it.

The film’s director Udayan Prasad says it was actually Kristen’s knock-out audition at the Chateau Marmont that attracted his attention immediately and let to her casting in the movie starring William Hurt and Mario Bello.

“She has a terrific presence Kristen does,” he tells PopEater. “She walked into the room. You just sensed something, like who is that person?

“Art [Cohn] probably talked to Jodie Foster after we had met Kristen.”

Indeed, a source close to Foster tells PopEater that it was Cohn who brought up the idea of casting Stewart during a phone conversation. “Arthur was the one who mentioned Kristen and Jodie said, ‘Oh my God she would be great,’ ” says the source. “It’s wasn’t her idea.”

“But Jodie did say that Kristen would be really good for it.”

Kristen Stewart was a pre-“Twilight” 17 years old when she filmed the coming of age drama “The Yellow Handkerchief,” with British actor Eddie Redmayne in New Orleans, a film due out later this month. But the two stars revealed to AccessHollywood.com on Thursday that Kristen learned her first details about her then-upcoming co-star Robert Pattison from Eddie, who turned out to be a R-Patz pal.

“Randomly, at the end of this, you were about to do ‘Twilight,’” Eddie said, turning to his “Handkerchief” co-star Kristen during Access’ interview. “I had known Rob since I was [younger]. So I was like, ‘Yeah! You’re working with my mate Rob!’ You’re like, ‘Really? What’s he like?’ I was like, ‘He’s a good boy.’”

Kristen said although she first attempted to find out more about her “Twilight” co-star from his pal, she realized Eddie’s lips were fairly sealed.

“I sort of got from [Eddie] that they were friends for a long time and he wasn’t going to say anything bad about him. Even if there was something bad, it was just sort of like, ‘Yeah, it’ll be good,’” Kristen laughed.

Eddie confirmed he and his British boys club buddies stick together, a group that includes Eddie, R-Patz and “Vanity Fair” actor Tom Sturridge.

“They’re like, so almost incestuous,” Kristen said.

“It is incestuous,” Eddie laughed. “Rob and Tommy Sturridge and I – we’ve all been at it for a while now and it [is] so funny what happens when you start doing the jobs and you work with other people and you realize the whole industry is incredibly incestuous.”

While Eddie didn’t have his triumvirate on set with him on “The Yellow Handkerchief,” which also stars Maria Bello and William Hurt in a troubled love story, the Brit was taken into a new group – the Stewart Family.

Due to her age at the time, Kristen’s family lived with her while she played the part of Martine, a lost 15-year-old, and when they realized Eddie was an Englishman alone in New Orleans, they took him out.

“I remember your family [was] there as well. I was like, all by myself and Kristen kept thinking I was this sort of lost British loner, but I remember it was Mother’s Day or something and we went into The Quarter…”

“And had brunch,” Kristen chimed in.

“Her family invited me to Mother’s Day,” Eddie said smiling.

But it was while making the moving story, set across a post-Katrina New Orleans, that Kristen realized she values being older and independent, for the purposes of work.

”[Eddie was] living in New Orleans in an apartment – he’s not been in that city before. I was like, ‘God, you’re alone. I have my parents and my brothers,’” she recounted. “Now I would be like, I have to…”

“Get away,” Eddie filled in.

“You need concentration,” Kristen added of how she focuses on work. “It’s like, I need to get as close to him as I possibly can, so I don’t need my brother being like, ‘When are you coming home?’”
