It was also revealed that Annie Parisse will play Paterno's daughter and Riley Keough will play Sara Ganim, the 23-year-old journalist who reported on the scandal. He becomes involved in his assistant coach Jerry Sandusky's sexual abuse scandal, which leads to his credibility and legacy being questioned and criticized.
Paterno was dismissed by Penn State in 2011 in the wake of the Sandusky child sex abuse revelations.
Al Pacino will bring a one of college sports' fallen stars back to Earth.
Paterno died in early 2012 of complications from lung cancer.
This will not be the first time Pacino, 77, has worked with HBO and Levinson.
Barry Levinson will direct the movie that is sure to open fresh wounds in the College Station community and beyond, where Paterno supporters are still legion.
Pacino has starred in other HBO films like the Jack Kevorkian biopic, "You Don't Know Jack", and "Phil Spector".
It's no different with the late Nittany Lions coach. Sandusky was convicted on 45 counts of child molestation in June 2012.
