Danes has won three Emmy and four Golden Globe trophies for playing the lead role of CIA agent Carrie Mathison on the popular show.
Nimrat, 32, and 'Life of Pi' star Suraj Sharma are the new additions to the fourth season of the hit thriller series. Nimrat will make her debut on the fourth episode of season 4.
The actress won international acclaim for playing a lonely housewife in Ritesh Batra's 'The Lunchbox'. Nimrat, however, believes 'Homeland' would be her real introduction to the western audience.
"'Lunchbox' was an incredible gift for all of us, mostly for Ritesh and me but I feel 'Homeland' would be my real introduction to the western audience because it already has a great viewership and fan following. I feel I have a big responsibility to be as true to the story as possible," Nimrat said.
"It was completely out of my comfort zone. Everything was up in the air. Normally, I am used to working after doing a lot of rehearsal but we were given the script just before shooting. It felt like I was doing a workshop," she said.
