Colin Firth (as Harry Hart) wears Cutler and Gross tortoiseshell acetate square-frame sunglasses in the 2015 spy movie Kingsman: The Secret Service. These glasses are hand-crafted in Italy from tortoiseshell acetate in a distinguished square-frame shape.
The arms are meticulously stamped on the inlay with the Kingsman logo and 'Galahad' - the code name of the character Colin Firth plays in the film.
