Hey guys can someone please help me find the name and this movie I watched on a cassette, it looked oldish maybe 1980 or 1990 something. Basically what I can remember is that there is a man and a woman and they have this child and around 4 -5 years old he gets hit by a car or truck and dies, I remember he was wearing a jean dungaree and he had blue eyes and blonde hair. After he gets buried in a little coffin and weird shit starts to happen. Then the dad dug into his coffin and the body as not there. Please help me the movie seemed to me to be scary.
