In addition to writing and directing the series, Peterson reprises his role as Dug from the film. Ed Asner, Carl's voice actor from both the film and the series, died on August 29, three days before the series premiere, making it a posthumous performance and is dedicated in his memory. Unused archive recordings of Jordan Nagai as Russell were used in the episode "Science", as Nagai had already retired from acting by the time the series entered development.
Bob Peterson has been a household name at Pixar Animation long before his Dug days. He was first hired by the studio back in 1994 as an animator for commercials before being catapulted straight into production on Pixar's first major feature film, Toy Story (1995). From there, Peterson went on to juggle work as both a voice actor and a writer for Pixar for many years to come. He voiced Geri in the memorable chess animated short Geri's Game (1997), Roz in both Monsters Inc (2003) and Monsters University (2013), Mr. Ray in both Finding Nemo (2003) and Finding Dory (2016) and of course Dug in Up (2009), which he also co-wrote. 781b155fdc
