The Scottish actor was tremendously impressed by the acting talents of Tom Holland, Samuel Joslin, and Oaklee Pendergast and he insists the youngsters have a very bright Hollywood future ahead of them.
The actor says, ""I've seen directors actually scare children to provoke a reaction... I don't know what their concept of acting might be but they were extraordinary. There was a great understanding of pretend and reality.
""They called me and Naomi (Watts) mum and dad on set but they liked that because it was a game and it was funny. It helped to create this family that we have to believe in.
""Oaklee was ad-libbing lines all the time and he had real tears streaming down his face in scenes. They gave these incredible performances, these little people.""
