Answer
The answer is Signs, a 2002 American science fiction thriller film directed by M. Night Shyamalan. Charlie Sheen's role in "Scary Movie 3" was a parody of this film, specifically the character of Graham Hess, played by Mel Gibson in the original movie. The parody in Scary Movie 3 humorously exaggerates and satirizes various elements from Signs, poking fun at its plot, characters, and iconic scenes.
