Keira Knightley has developed an irrational fear on film sets that reduces
her to a crying wreck - firing fake machine guns.
The British actress discovered her weakness while shooting upcoming movie
DOMINO - which centres on the real-life story of model-turned-bounty hunter
DOMINO HARVEY - when she fell to the ground in tears.
And bizarrely Knightley can offer no explanation for her firearm
She says, "I hated firing the machine gun in Domino. I burst into tears. I
fell to the ground and couldn't get up. Don't know why. I know they say when
you experience something like that, it's like falling off a horse - you should
get back on
"I have fallen off a horse and I didn't get back on. I'm scared of horses
- I thought, that thing didn't want me on its back. I get that. I just don't
need to get back on."
