Keira Knightley has revealed the best way to seduce her.

The 'Atonement' star thinks that a good sense of humour in a man is very attractive — so making her laugh is the way into her bed.

"I think people get laughed into bed, don't they?" the actress revealed to Total Film magazine while promoting her upcoming movie 'The Edge of Love' about the poet Dylan Thomas.

Although the 'Pirates of the Caribbean' star doesn't believe the late Welsh poet was handsome, she understands how his poetry could have attracted women.

"Dylan Thomas did shag around but you look at pictures of him and he was no hunk. However, his poetry is extraordinary. He's a mischief-maker, a puck. He just wants to prod and see what happens," she said of the poet, played by Matthew Rhys in the film.

"There is a spirit and a sexiness to Matthew Rhys' Dylan that's quite dangerous because you know he's a s**t. But that doesn't mean he's not attractive. Do you think only nice blokes get girls into bed?"
