Ben Affleck let Gone Girl cast use his Porsche

Ben Affleck let the ‘Gone Girl’ cast borrow his Porsche.

The 42-year-old actor used to leave the keys of his supercar for the cast members of the crime thriller movie to use if he wasn’t there, according to his co-star Casey Wilson, who admitted she sees the Hollywood hunk as a ”real-life hero” after acting alongside him.

She said: ”He was so nice. He let us borrow his car when he went out of town. It was really nice.

”All the actors were sharing two cars, and so he very kindly left his keys at the front desk for a bunch of us to use on the off-week when he was out of town. So he’s a hero. He’s a real-life hero in my book.”

Casey – who plays Ben’s on-screen neighbor, Noelle Hawthorne, in ‘Gone Girl’ – admitted the cast used the star’s car, which she thought was a Porsche, to travel to a local nightspot in Missouri, where the thriller was filmed, so they could ”go crazy” in between filming.

Speaking to HuffPost Live, she added: ”We went to what we called the ‘Tarbucks,’ which is a Target slash Starbucks.

”That was right across the street, and that was a big night. That was like, ‘Let’s blow the roof off this place and go crazy.’ ”

Casey is not the only fan of Ben from the film as his on-screen mistress Emily Ratajkowski (Andie) recently admitted it felt ”surreal” locking lips with the movie legend in the motion picture.

The 23-year-old stunner said: ”The whole experience was a little surreal.

”I have to be honest. Obviously Ben Affleck is one of those – you know his face. I grew up with his face. Not sure if he would love that.”
