'Harry & Snowman' Trailer Recounts Show-Jumping Champions' Cinderella Story (Exclusive)

The documentary is set to premiere at the well-regarded Full Frame Documentary Film Festival in Durham, N.C. on Saturday.

Duke's NCAA tournament-winning men's basketball team won't be the only championship story to get a high-profile reception in Durham, N.C. this week.

Feature-length documentary Harry & Snowman, which is set to premiere at Durham's well-regarded Full Frame Documentary Film Festival on Saturday, tells the story of how Harry deLeyer rescued an old Amish plow horse, Snowman, for only $80. The two of them became show-jumping champions and media sensations in the late '50s and '60s. The film marks the first time deLeyer has told his life story.

The official re-cut, re-scored trailer, which The Hollywood Reporter is premiering exclusively, features deLeyer recalling how he knew he found a special horse in Snowman and how Snowman became like a member of his family. The video was scored by award-winning composers Joel Goodman and Elik Alvarez.

In addition to winning show-jumping prizes, Snowman appeared on Johnny Carson's Tonight Show and the game show To Tell the Truth. He had his own fan club and was the subject of three best-selling books. Snowman died in 1974 but was posthumously inducted into the Show Jumping Hall of Fame in 1992.

Harry & Snowman's premiere screening on Saturday already has sold out. But the festival will be rescreening the film on Sunday at 2:20 p.m. Tickets for that screening are available here.
