He's known for playing suave Secret Service agent James Bond, but Pierce Brosnan traded in his signature slicked back strands for something a little more scruffy.

The 69-year-old actor was spotted wearing a gray wig with tendrils cascading down to his shoulders while walking on set of his latest film, "Four Letters of Love."

Brosnan stars alongside Helena Bonham Carter and Gabriel Bryne in the romantic flick, based on the Niall Williams bestselling novel of the same name.

"Nicholas and Isabel were made for each other, but how will they ever know it? As ghosts, fate and the sheer power of true love pull them together, so too does life threaten to tear them apart," a synopsis described the movie on IMDb.

The "Black Adam" star was born in Ireland and studied acting in London before moving to the United States in the '80s.
