Dorothy's red shoes did not represent anything. In the original novel, she had silver shoes (silver to represent magic). When they turned the novel into a film, they changed the shoes to red to take make them stand out more since the film was going to be in colour.

In the classic film, the red shoes can't stop dancing; the wearer cannot take them off either. Moira Shearer plays the dancer Victoria Page; see her bio in Wikipedia; it has links to the entries about the movie, The Red Shoes.

The original 1948 film, "Red River" was directed by Howard Hawks.

The remake of the movie which was only screened on TV, was directed by Richard Michaels and released in 1988.

The duration of In Her Shoes - film - is 2.17 hours.

There would be no way of knowing the answer to that.
