Sanders's account tweeted a still from the 2014 film in a tweet commemorating the 51st anniversary of the march, as first reported by Politico.

Politwoops reported on Monday that Sanders’s account kept the flub live for 26 minutes before taking it down.

“Bloody Sunday was about showing the entire world how far some would go to prevent African Americans from voting,” the tweet said, according to the site, which documents politicians' deleted tweets.

Sanders’s tweet featured a cast photo from the movie recreating the march, Politwoops said.

Sanders's Twitter account still has two tweets up discussing the significance of the 1965 march. 

Civil rights activists organized three marches from Selma, Ala., to nearby Montgomery in 1965 to raise support for the Voting Rights Act.

“Selma,” a best picture Oscar nominee, came out in 2014 and starred David Oyelowo as Dr. Martin Luther King, Jr. and Carmen Ejogo as his wife, Coretta Scott King.
