''Jack Frost'' is a 1998 family film directed by Troy Miller, starring Creator/MichaelKeaton. Jack Frost (Keaton) is a workaholic rock singer who's on the road most of the time so he can't spend a lot of time with his wife Gabby (Kelly Preston) and son Charlie (Joseph Cross) and constantly breaks/forgets the promises he made to them. One evening, Jack decides to abandon his gig and borrows his best friend (and the band's keyboardist) Mac [=MacArthur=] (Creator/MarkAddy)'s car to go home and spend the holidays with his family. Unfortunately, a bad storm begins block Jack's view, and due to the faulty windshield wiper, Jack crashes his car and is killed instantly.

One year later, the spirit of Jack finds himself reincarnated in a snowman's body. This is in order to allow father-son bonding that had never quite happened in Jack's human life.

Under no circumstances is it to be confused with an [[SimilarlyNamedWorks identically-titled]] [[Film/JackFrost1997 film that came out the preceding year]].

** One scene had the titular snowman receive two snowballs to the chest during a snowball fight. He [[ManIFeelLikeAWoman gropes himself for a second]] before throwing them away.
** And when making a snowman, Jack pretends he misunderstood about where to attach the carrot. This one later comes back to bite him when he becomes the snowman, looks down to find out in his own horror that he has no genitals.

* LazyBum: Mac [=MacArthur=], Jack's eccentric keyboardist who moves into the Frost's house after Jack's death, spends most of his time on the sleeping on the couch. However Mac's laziness could very likely be mostly out of his own grief for Jack.
