In linguistics, backchannels are listener responses that can be both verbal and non-verbal in nature.

The term backchannel was designed to imply that there are two channels of communication operating simultaneously during a conversation. The predominant channel is that of the speaker who directs primary speech flow. The secondary channel of communication (or backchannel) is that of the listener which functions to provide continuers or assessments, defining a listener's comprehension and/or interest.

Due to research development in recent years, backchannel responses have been expanded to include sentence completions, requests for clarification, brief statements, and non-verbal responses and now fall into three categories: non-lexical, phrasal, and substantive.

Backchannel communication is present in all cultures and languages though frequency and use may vary. Confusion and/or distraction can occur during an intercultural encounter if participants from both parties are unfamiliar or unaccustomed to the backchannel norms of the opposing communicator.

The Good, the Bad and the Ugly (Italian: Il buono, il brutto, il cattivo) is a 1966 Italian epic Spaghetti western film directed by Sergio Leone, starring Clint Eastwood, Lee Van Cleef, and Eli Wallach in the title roles. The screenplay was written by Age & Scarpelli, Luciano Vincenzoni and Leone, based on a story by Vincenzoni and Leone. Director of photography Tonino Delli Colli was responsible for the film's sweeping widescreen cinematography and Ennio Morricone composed the famous film score, including its main theme. It is the third film in the Dollars Trilogy following A Fistful of Dollars (1964) and For a Few Dollars More (1965). The plot revolves around three gunslingers competing to find a fortune in buried Confederate gold amid the violent chaos of gunfights, hangings, American Civil War battles and prison camps.

In a desolate ghost town during the American Civil War, bandit Tuco Ramirez ("The Ugly," Eli Wallach) narrowly shoots his way past three bounty hunters to freedom, killing two but only badly wounding the third. Miles away, Angel Eyes ("The Bad," Lee Van Cleef) interrogates a former soldier called Stevens (Antonio Casas) about a missing man named Jackson who has taken on the name "Bill Carson" (Antonio Casale) and a cache of stolen Confederate gold. He brutally guns down Stevens and his eldest son after the interrogation, but not before Stevens pays Angel Eyes to kill Angel Eyes' employer, another former soldier named Baker. Angel Eyes later collects his fee for Stevens' killing from Baker, and then shoots and kills him, too.
