'The International' actress - whose stunt double suffered an injury while filming one of the thriller's adrenalin-fuelled chases - is happy to leave the dangerous scenes to someone else.
Naomi said: "I have no interest in trying stunts myself. It was hard enough lying on a cold piece of road - that's a stunt as far as I'm concerned."
In the new movie, the 40-year-old actress plays Assistant District Attorney Eleanor Whitman who joins forces with an Interpol Agent, played by Clive Owen, to fight a corrupt banking system.
Naomi, who gave birth to her second son Samuel Kai in December, is finding it hard to balance her career with the demands of a newborn.
She said: "I had just had a baby, so it was quite an adventure for me, travelling with my new baby everywhere. I had to express milk and send it back to the hotel and then feed him all day long, so it was tough - I didn't get a lot of rest."
Naomi and her partner, actor Liev Schreiber, also have a one-year-old son, Alexander.
