According to the National Enquirer, a source said that Pattinson was riding the elephant, Rosie, in a scene for 'Water For Elephants' when she was instructed to step forward but she instead lay down and rolled over.
A source said: "The script called for the elephant to step forward while swinging her trunk from side to side, but Rosie got her signals mixed up."
"Instead, she sat down on her big butt, lifted her front legs - then rolled over."
"Before anyone could react, Robert slid right down the elephant's back."
"It could have been a disaster if she'd rolled over on him - but he got lucky, landing face first in a pile of dirt and mud. He was filthy, but unharmed."
