Emmett Till's Mother Fights for Justice in Powerful First Trailer for Biopic Till

Emmett Till, then 14 years old, was savagely beaten and killed by white men in Mississippi in 1955, and his passing sparked the civil rights movement.

An emotive new movie retells the true tale of Emmett Till and his mother's struggle for justice following his death.

The first trailer for the movie Till, which is about the 1955 lynching of Emmett, a 14-year-old boy in Mississippi, was released on Monday by MGM Studios.

His body was then dumped into the Tallahatchie River as a huge metal fan was tied around his neck with barbed wire.

The trial for Emmett's murder involved Donham's then-husband Roy Bryant and Bryant's half-brother J.W. Milam.

The civil rights movement was sparked by Emmett's death, and his mother Mamie Till-

Mobley is renowned for insisting on an open-casket burial because she "wanted the world to see what they did to my baby."

For his book The Blood of Emmett Till, Timothy B. Wilson interviewed Donham in 2007, 

After premiering in a few cinemas on October 14, Till will be released nationally on October 28.
