Washington, Mar 24 : American actor David Schwimmer had to keep a look out for British actress Thandie Newton on the set of his directorial debut 'Run, Fatboy, Run', as she was always playing pranks.
The former Friends star was determined not to fall for any of Newton's tricks which her co-star Simon Pegg had to endure.
"Thandie Newton was the queen of the pranks," Contactmusic quoted Schwimmer as saying.
"When Simon was on set working, she would put cellophane on his toilet so when he went to go to the bathroom he splashed everywhere. She would take old underwear and rub it with Marmite and put it in his trailer... It was pretty disgusting," he said.
"I think the best one was when we were doing the press junket together in London, where the movie opened. Thandie, Simon and I were in three different rooms with all these on camera interviews.
"Thandie had got there hours before Simon and I, and she had filled every one of his 12 giant bottles of water with vodka. So when he was in the middle of his first interview on camera and he goes to take a (swig) during the interview, a huge gulp and just spits up everywhere all over the interviewer. That was probably the best prank," he added.
