Residuals are an essential issue in the current strikes of Hollywood's actors and screenwriters. The term refers to long-term payments negotiated by unions that contributors receive for movies and TV series that are viewed after their initial release. The payment varies vastly depending on how and where their shown. Some can make millions, others just a few cents. The unions say the switch to streaming has gutted residual payments that especially working class actors depend on. The studios that employ actors and writers say their most recent contract offer includes generous increases in the payments.
