Matthew is played by Chris Haley, the son of director/co-star Jackie Earle Haley.
Jackie Earle Haley's directorial debut.
Reunites Rob Brown and Michael Pitt after appearing in Finding Forrester (2000), fifteen years earlier.
Dan Stevens (Noah), Edi Gathegi (Marques), Jackie Earle Haley (Gerry), and John Travolta (Eddie) have all played comic book characters in movies and on tv. Stevens on Legion, Gathegi on X-men: First Class, Haley on The Watchmen, and Travolta on The Punisher.
Travolta first meets the four guys at The Royale. This is most likely a reference to the scene from Pulp Fiction where Vincent tells Jules about a Big Mac being called a "Royale with cheese".
