Snubbed dwarfs are raging at the makers of Hollywood film "Snow White and the Huntsman" for casting average-sized people as the film's seven dwarfs.

The dwarf actors are threatening to protest against the film -- which stars Oscar-winner Charlize Theron -- with a "100-midget march," according to a report in TMZ.

Los Angeles dwarf theater group Beacher's Madhouse is fuming -- arguing that filmmakers would never use white actors and then digitally turn them black.

Matt McCarthy -- a 4ft, 1in dwarf who heads the group -- fired off a letter to Universal Chairman Adam Fogelson, saying, "In response to and in protest of this incredible injustice and prejudice, the Beacher's Madhouse midgets and I are coordinating a 100-midget march to Universal's offices."

McCarthy adds that casting average-sized actors as Snow White's dwarfs "is the equivalent of Universal casting a white actor to play a role written for an African-American person and digitally changing the color of their skin".

Another dwarf group, The Little People of America, said the entertainment industry should be actively casting little people.

A spokesman said, "This means both casting people with dwarfism as characters that were specifically written to be played by little people ... and other roles that would be open to people of short stature."

In the film, the dwarfs are played by actors Ian McShane, Bob Hoskins, Toby Jones, Eddie Marsan, Brian Gleeson, Ray Winstone, Nick Frost and Johnny Harris.

Director Rupert Sanders used camera angles and special effects to make them appear like dwarfs, including digitally inserting their faces on to the bodies of shorter people.
