Former bank executive Ellie Ngim, 31, is living her dream - she is making films for a living now.

After she left her job, she used to take part-time courses in the craft and, for a time, was picking up skills from the ground up - literally.

"I got really good at sweeping floors," says the graduate of the London School of Economics. Her job as a production assistant on film sets also saw her ironing costumes, for $120 a day, if she was lucky.
