A film set to premiere at the Sheffield International Documentary Festival in England this month documents the story of an eccentric Utah filmmaker who has made 200 low-budget movies in the past two decades.

The Daily Herald reports the documentary film “The Insufferable Groo,” made by Brigham Young University film professor Scott Christopherson, follows Stephen Groo’s life as he films “The Unexpected Race,” an elf-human love story.

The Provo independent filmmaker has developed a Hollywood fan base and recruited actor Jack Black to star in his 2016 movie.

Christopherson says Groo “grew up just loving watching movies, loving everything about them, grew up trying to make movies.”

A Provo screening of the documentary is being planned for later this year.
