Harry Potter star Ian Hart felt terrible for one young mum on the set of his new film A BOY CALLED DAD - because her triplets were always cold, soaking and in peril.
The unnamed mum agreed to let her babies alternate as the child star of the movie - but Hart feels sure she had no idea what was expected of the tots.
In one scene, his movie son, Kyle Ward, was standing on the edge of a cliff in wind and driving rain - with one of the babies cradled in his arms.
The Backbeat star says, "We did some of that scene with a doll and then we did the rest of the scene with the baby. The mother of the baby was watching it get further and further away from her arms and closer and closer to the edge of a cliff handled by a child, effectively.
"What was going through her mind I don't know! It was raining and it was wet and slippery... We had rain galore and wind.
"The poor little baby was getting rained on. It was freezing cold and the baby was crying; by take two this little baby was soaked! His little face was covered in water. It was terrible."
