London, April 29 (IANS) To cut the costs, actress Naomi Watts who plays a mum-to-be in the film 'Mother and Child' agreed to show off her real pregnant belly and now is thrilled to watch the magical moment on screen.

'Here I had this growing belly and we needed a few shots but we actually only used one. It was a no-brainer because prosthetics never look convincing enough and the good ones are really expensive and this was a tiny budget, so Rodrigo popped on a plane and came with his cinematographer and he stole that shot,' imdb.com quoted her as saying.

'Now, when I watch it, I get very emotional because it was that moment between me and my baby and you see a little bit of movement because I drank some ice water and shook him (baby) up,' she added.
