And now she's warming up to the idea of hearing herself speak in her own voice.
"It really does add to the performance, honestly. Now I'll be insisting on my own dubbing. Now when I look back on the movies where someone else dubbed for me I go, 'No no no! That's not me! But in Namaste London and now Apne I felt I was watching AND HEARING myself."
From hearing professional dubbing artistes speaking for her in Ram Gopal Varma's Sarkar although she was assured her own voice suited the foreign-returned character just fine, to synchronizing voice and personality in her latest releases Katrina has come a long way in two years.
"Whether it's Telugu, Malayalam or Tamil I feel the Indian film industry has given me back to me more than I've given it. I couldn't have asked for more."
She feels completely at home in Bollywood. "Every unit has its rhythm and atmosphere. I mean a Vipul Shah production is very different froma David Dhawan set-up. But I don't think I ever went into my van for either Namaste London or Partner. With Vipul I go blah-blah all day long."
But Katrina admits it gets lonely for her. "I do miss my family at the end of the day. When I get really home sick I take off for Chennai to meet my mother and sisters.
Sometimes just being on the makeup chair gets too much I take two weeks off for my family. Luckily I've never had an awkward moment in Mumbai. I know not everyone is nice. But I've had no ugly moments. Everyone has been welcoming and encouraging.
So has the seemingly unapproachable Katrina turned talkative on the sets? "If I get along with the unit I talk until people run away. Ha ha. I think I'm happy with my progression. I need to work harder."
She recently shot a song with Abbas-Mustan for Race. "It's so much fun to be on the sets with actors like Saif and Bipasha. They don't make me feel unwelcome for even a second."
