Herzog strongly urged the "Mandalorian" filmmakers to use the puppet for the character and not computer-generated imagery. Favreau and executive producer Dave Filoni shot scenes for the Child both with and without the puppet, so they could replace the character with a CGI effect in post-production if the puppet did not look satisfactory. After Herzog filmed a scene with the Child, Filoni began to remove the puppet to shoot another alternate scene without him, but Herzog urged him not to do so and to remain committed to the animatronics and puppetry, saying: "You are cowards. Leave it. Leave it." When this story was later told to the public, some media reports mistakenly described it as if the producers of "The Mandalorian" were entirely replacing the Child puppet with a CGI creation altogether until Herzog convinced them otherwise. Carl Weathers, the actor who portrayed Greef Karga, said that although his character's personality was normally self-assured, he deliberately made him act more cautious and nervous in his scenes with Herzog in order to convey that the Client was a dangerous man. Weathers was a great admirer of Herzog, referring to him as "maestro" on the set of "The Mandalorian", and the two had extensive conversations with each other about Herzog's past films and his relationship with actor Klaus Kinski. The Client character and Werner Herzog's performance have received generally positive reviews from critics. Nick Venable of "CinemaBlend" said the character "was a scene-stealer from the start" and that he wished he had been featured more prominently in the season. John Serba of "Decider.com" called Herzog a significant casting coup for "The Mandalorian", and said the Client's "steely, dread-drenched, multi-layered, gravely philosophical dialogue" seemed specifically tailored for him. Serba praised the actor's performance, writing: "He delivers the heft with a deeply furrowed glower, and we feel it in our marrow." Scott Snowden of "Space.com" described Herzog as "magnificent" in delivering the Client's monologues. /Film writer Ethan Anderton said Herzog "makes the perfect crime boss" and has a "unique cadence and screen presence" which made him a good fit for "The Mandalorian", which sought to explore a darker side of "Star Wars". Likewise, "Dazed" writer Thom Waite said Herzog's "menacing presence" fits in well with the darker tone that "The Mandalorian" attempts to set for the "Star Wars" franchise.
