The film is about a bear from Peru, who is adopted by a family after they find him lost and alone at the London railway station, reports contactmusic.com.
"Paddington will be computer generated, and I will speak his lines with, I suspect, a slight Peruvian flavour," Daily Mail quoted Firth as saying.
"Every other character in the film will be real, live, human beings. But the idea is that Paddington will have something of me in his DNA because I'm going to do some sessions wearing one of those helmets with cameras to capture my face muscles, and all that data will somehow be incorporated into Paddington," he said.
"Then they'll use motion-capture equipment on someone more bear-size than me to do all the full body, bear stuff," he added.
The movie also features Nicole Kidman in the negative role, while Hugh Bonneville will be seen as the head of the family, which adopts Paddington.
