Jack Frost is a 1998 Christmas comedy fantasy drama film, starring Michael Keaton and Kelly Preston. Keaton stars as the title character, a man who dies in a car accident and comes back to life as a snowman. Three of Frank Zappa's four children--Dweezil Zappa, Ahmet Zappa, and Moon Unit Zappa—appear in the film.
The costume for Jack Frost's snowman form was created by Jim Henson's Creature Shop. More: en.wikipedia.org.
