Playing a mother on the big screen for the first time might've given Rachel McAdams
a taste for becoming a mom herself.
"Having a few [kids] would be great," McAdams told PEOPLE at the New York City premiere of The Time Traveler's Wife
on Wednesday, adding that she's "looking forward to it someday."
Playing opposite Eric Bana in the romantic drama, the Canadian actress says it was a role that she very much enjoyed. "I was excited and nervous about it because I haven't done it before. It was a welcome challenge," she said. "The little girls [Hailey McCann and Tatum McCann] in this film were so fantastic. They are real sisters and they made my job really easy. So I didn't have to work too hard at that."
When the day does arrive for McAdams, 30, to be a mom, she hopes to have the same qualities as her own mother. "My mom is a great inspiration to me," she said. "She's a nurse and very nurturing and gentle. She lets me be who I am. Hopefully I can take on those qualities and be as great as her."
Wearing a white Pucci dress with a plunging neckline, McAdams walked the red carpet solo and, when asked about reports she recently split with boyfriend Josh Lucas, she would only say, "I'm sorry but I don't talk about my personal life."
When pressed for the best way to cope with heartache or breakups she said, "It's different for everyone. If it's eating ice cream, do what you love. Just have a good time. That's what I would do."
