Trivia / The Sylvester and Tweety Mysteries

• In Memoriam: The series, season one in particular, was done in Friz Freleng's honor.
• Keep Circulating the Tapes: Season 1 is on DVD, but there's been no word on releases of the later seasons. However, Boomerang still airs reruns of the show time and again, and all seasons are available to download on iTunes, at least in the United States.
  • Rescued when the entire series became available on HBO Max in 2020.
• Kids' Meal Toy: Carl's Jr. and Hardee's had a set of five toys in 1998. There was a pull-back roller, a runaway chair, a chase scene top, a Sylvester squeeze squirter, and Tweety's "The Chase is on" viewer.
• Missing Episode: The final episodes, "The Tail End?" and "This is the End," were meant to air in 2000, but the show was cancelled before they could air. They didn't air on television until December 18, 2002 on Cartoon Network.
• The Other Darrin:
  • Yosemite Sam is voiced by Jim Cummings (1952) in the first season finale, "Go Fig". Later episodes have him voiced by Maurice LaMarche.
  • Joe Alaskey replaces Greg Burson as Daffy Duck in this series and would remain as Daffy's go to voice actor from here until 2010. Alaskey also replaces Bob Bergen as Tweety's voice actor at this point and would voice him in various projects until 2003.
  • Billy West voices Foghorn Leghorn instead of his usual voice actor Greg Burson.
• Recycled Script: A number of episodes are essentially remakes of older cartoons. For example, "Good Bird Hunting" borrows heavily from Pete Puma's debut cartoon, "Rabbit's Kin," only with Tweety in Bugs' role.
• What Could Have Been: In her autobiography, June Foray states that the producers were originally hesitant about having her playing Granny, even asking her to audition for a character she'd been playing for decades. Luckily for June, Chuck Jones got wind of this and took them to task: "How dare you use a fake Granny!?" . The producers then gave June the part.
