Marcel Emile Gaston LePlat (December 2, 1913 – March 29, 2014), known professionally as Marc Platt, was an American ballet dancer, musical theatre performer, and actor.

Born Marcel Emile Gaston LePlat to a French immigrant father in Pasadena, California,[1] he was one of the original members of the Ballet Russe de Monte Carlo, performing under the name Platoff.

He is the cowboy friend who buys Curly's saddle for $10 at the auction - and who also comments that, the previous year, Ado Annie's sweet potato pie gave him a 'three day bellyache' (Platt is credited in the cast list of the film as a dancer).

After he stopped dancing, Platt served as the director of the Radio City Music Hall Ballet for several years, then transitioned to full-time teaching.

In 1951, Platt married dancer Jean Goodall who died in 1994; the couple had two children, Michael and Donna.
