While filming the sci-fi sequel, Carrie-Anne injured a leg two weeks into rehearsals - and was forced to spend six weeks hopping around on her one good leg.
But whenever she tried to rest her sore limb, Reeves showed not a shred of sympathy, she tells Esquire.
"He'd call me lazy," she says. "If I sat down and tried to take a break, he'd say, 'What are you doing?' It kinda drove me crazy."
And that wasn't the only thing that had Carrie-Anne climbing the walls. She says her steamy nude scene with Keanu was tough to shoot.
"I'm such a private person, and sexuality is such a private thing," Moss says.
The self-conscious starlet also says that she sobbed through an early screening of the first Matrix flick.
"I just can't stand my voice sometimes, or how my face looks," she says.
