Oscar and Emmy winner Melissa Leo is joining the cast of “Supermax,” the upcoming action-thriller starring Will Smith. Amazon MGM Studios and Miramax are producing the film, which is directed by David Gordon Green. Leo’s role has not been disclosed.
The movie centers on two FBI agents who investigate a murder that appears impossible, taking place within a maximum-security prison known for being difficult to penetrate. Both outlets report that Leo joins an ensemble that already includes Smith and other previously announced cast members, though specific co-stars beyond Smith are not detailed in the excerpts provided.
Variety and ComingSoon.net both frame the announcement as a cast addition for the same production and confirm the main creative team (Smith and Gordon Green) and the shared premise involving the investigation and the prison setting. The only notable difference is that ComingSoon.net explicitly credits Variety for the casting update, while Variety presents it as an exclusive announcement; neither outlet provides further details about Leo’s character or other plot specifics.
