Bradley Cooper, Ryan Gosling competed for sexy title on set

Cooper, 37, says they judged each other on everything from walking to opening doors, reported Sun online.

"It was treacherous. We had 'Sexiest Man Alive' matches every lunchtime. Who walked most sexily, who ate lunch most sexily, who opened doors most sexily," Cooper said.

However, it was Gosling who took the title every time, says Cooper.

"He won every time," he said.

"The Place Beyond Pines" is directed by Derek Cianfrance and is expected to release in March next year in the US.
