AceShowbiz - Leonardo DiCaprio and Steven Spielberg may reunite for an epic biopic of Ulysses S. Grant. "The Wolf of Wall Street" actor and "The Post" director are reportedly in talks to take on an adaptation of Ron Chernow's "Grant", with DiCaprio possibly starring and Spielberg eying to direct. The two previously worked together on 2002's drama "Catch Me If You Can".

Deadline reports that Lionsgate and DiCaprio's Appian Way acquired the rights to "Grant", the bestselling biography of the American Civil War general and the 18th president of the United States, last November. David James Kelly, who recently wrote Appian Way and Lionsgate's "Robin Hood" remake, is adapting the book into a script.

Chernow won the 2011 Pulitzer Prize for Biography and the 2011 American History Book Prize for his 2010 book "Washington: A Life". He also wrote "Alexander Hamilton" (2004) which became the inspiration for Lin-Manuel Miranda's Tony-winning musical "Hamilton".

As the site notes, DiCaprio and Spielberg's schedules are one of the key factors in making their next collaboration possible. DiCaprio has been tapped to star in Quentin Tarantino's "Once Upon a Time in Hollywood" which boasts A-list cast including Brad Pitt and Margot Robbie. Spielberg, meanwhile, has set "Indiana Jones V" and "West Side Story" remake as his next two films.

DiCaprio and Appian Way partner Jeniffer Davisson are producing, while Chernow is executive producing. No release date is set for the movie just yet, but the studio makes this project a priority.

DiCaprio took time off after filming "The Revenant" which earned him the Best Actor Oscar. As for Spielberg, the prolific filmmaker recently directed the awards-winning historical political thriller "The Post" and the critically-acclaimed sci-fi movie "Ready Player One".
