The 28-year-old actress was photographed wearing a leopard
print jacket and skimpy dress, as she works through several scenes opposite a man in a cowboy hat behind security lines, said the Hollywood Reporter.
In the film, Johansson plays a woman forced to become a drug mule.
"Lucy" is the biggest Hollywood production to shoot in Taiwan since local director Ang Lee's "Life of Pi".
Lucy is due to hit theatres in 2014. The project is being touted as a return to the director's heroine-led action of the 1990s, when he released "La Femme Nikita", "Joan of Arc", "The Professional" and "The Fifth Element".
