A first rate alien invasion/thriller movie from writer/director M. Night Shyamalan and starring Mel Gibson and Joaquin Phoenix. A former preacher Graham Hess (Gibson) is living in the rural Pennsylvania countryside as a farmer when he starts to experience strange phenomenon after a crop circle is discovered on his farm by his children. Along with his brother Merrill (Phoenix) and his children they begin to realize that an alien force may be preparing to invade the planet. Things may not be as they seem though in a classic Shyamalan twist of an ending after the aliens have invaded. The final question is do you believe in 'Signs'?
