Julia Roberts

Garry Marshall and his Runaway Bride co-stars Richard Gere and Julia Roberts had a communication breakdown on the set of the 1999 film - because both stars were so busy with their separate causes.

Director Marshall admits the chemistry on the set, that he'd experienced with the pair while making Pretty Woman with them a decade earlier, was difficult to come by - because the actors had become conscientious superstars.

The celebrated filmmaker says, "They suddenly both had cellphones and they put that on their ear and that was it - they were very busy.

"Richard, of course, is very close to the Dalai Lama... and Julia was really helping orphans in Jamaica and so once in a while I had to say, 'Anybody wanna make a movie here?' I was so afraid to interrupt them becauseI didn't wanna hurt the charities.

"They were more pre-occupied".

And Marshall reveals some of the film's romantic scenes had to be shot on days his stars wanted to be elsewhere "There was that one day that the schedules didn't work out and they were both upset - they wanted to go some place.

"So they couldn't look in each other's eyes.

"But nothing stops me. I got a kite... and they're both looking up and it looks like they're in love. "The next day they were happy.

In the end titles of that movie there's a scene in the snow that they were clearly so affectionate with each other".
