Hollywood stars ride naked through Athens

The naked man was none other than Sebastian Stan, the American actor who is known for his role as Bucky Barnes in Marvel's Avengers.

The 36-year-old actor rode along with co-star Denise Gough, as they filmed a scene from their upcoming film "Monday".

The actor seems to have frozen as heclenched his teeth because of the low temperatures prevailing in Athens.

The Irish co-star was stuck on Sebastian to warm up on the yellow scooter mounted on the back of a trailer.

The two actors were accompanied by members of the production crew - all dressed in thick clothes and also wore coats and gloves.

According to IMDb, the film "Monday" describes the story of "two self-destructive Americans who live between Athens and the Greek islands and eventually fall in love."

Sebastian Stan, however, seems to have been enchanted by Greece, as he has published photographs from the Corinth Canal and the Temple of Olympian Zeus in his account on Instagram.
