There is a movie Im looking for.. its about a teen boy who is a nerd in Highschool and his mother has a kid with her HS sweatheart. Years later she is married and his ghost comes back to life to help him become popular in order for his father to go to heaven. He teaches’em about girls, has magic powers and builds a red caddy ( i think its a red caddy). For example there is one scene where his father is carrying up the stairs because his son is drunk, and his stepfather see him leaning all funny but cant see his father’s ghost carrying him. Another seen the ghost father builds him a classic car fom a junkyard car. anybody know what movie this is?
