Preston will play Victoria Gotti, wife of John Gotti Sr. (Travolta). Ella, 11, will play their on-screen daughter Angel.
"The love and passion between John and Kelly ... will bring a huge benefit to John Sr. and his wife, and to tell you the truth, they have a lot in common. They both lost a child at a young age and they understand what the Gottis went thru when the Gottis lost their child," the film's executive producer Marc Fiore said.
Production is expected to begin in New York in the fall, with the film set to hit theaters in late 2012.
