Matt Dillon worked his crew so hard on the set of his directorial debut CITY OF GHOSTS - many ended up exhausted in hospital.

The movie hunk made the film on such a tight budget that he often had to ask crew members to put in extra time shooting street scenes in Cambodia to capture the essence of the country.

But his workaholic schedules almost cost him his team.

He says, "Shooting the film was difficult. We had a finite amount of money to work with and a difficult schedule. Of course, I did care about the crew. I care very much about them and appreciated their effort.

"You don't want to burn out the crew but we didn't any other option. We were up against it and people passed out from heat exhaustion. Some had to go to the hospital for IV drips."
