Sainsbury's “The Big Night” stars an eight-year-old girl giving her best performance for her mum. North Star is nervous initially, but she is backed by a cast of 59 other kids (from six to 11). All have the perfect Christmas-related costumes. As North Star gets more confident, the full cast is revealed, along with a 40 ft Christmas tree and 14 ft gravy boat. Their real parents were in the audience and were kept away until shoot day. This made their reactions so much more real. Tissue anyone?
