The Almost Famous star gave birth to Bingham, her first child with fiance Matt Bellamy, just two months before she began shooting the thriller and Hudson has heaped praise on filmmaker Nair for making time for her mum duties.
During an appearance on U.S. morning show Live! With Kelly and Michael on Tuesday (23Apr13), she said, "I was hiding in cylinders on set breastfeeding Bing and it was a really intense role so I was going from breastfeeding to bawling my eyes out. But it was a really amazing experience.
"Mira Nair is an amazing director, she's very maternal and sensual and she creates this very passionate vibe on set. And so she's rubbing my feet, talking about the script, as I'm breastfeeding Bing, on set, so it was really interesting. It was a really wonderful working experience."
