Sesame Street: A Very Grouchy Halloween

Sesame Street: A Very Grouchy Halloween is a Halloween special which first aired on HBO on October 20, 2019 to coincide with Sesame Street's 50th anniversary, with an additional broadcast on PBS three days later.

The night before Halloween, Oscar the Grouch receives an invitation to tour an old, haunted castle in Transylvania, once inhabited by Count von Count's long-deceased ancestor, the Grandcount Belugosi, which is said to have been abandoned for 200 years. Sesame Street's resident Grouch must take a 24-hour challenge and come face-to-face with ghosts who look (and act) eerily similar to the monsters, people and animals he lives with. If he fails to escape the castle by midnight, on the day after Halloween, he'll be turned into a ghost and trapped inside forever. Along the way, Oscar has to deal with the Grandcount's wicked great-granddaughter, the Countess Ohanna (the runt of the Count's family), who, backed up by Modo and Hugo (two gargoyles who are really bad at being evil), rules the Grandcount's domain with an iron fist. She feigns interest in marrying Oscar by tricking him into believing she is an honorary Grouch (with the intention of killing the Grouch soon after their marriage is finalized).

The exteriors (and some interiors) of the Grandcount's castle were filmed at the Jim Henson Company lot in Los Angeles, California, while the Sesame Street scenes (and most of the castle interiors) were filmed at Kaufman Astoria Studios in New York as usual. Sequences featuring stop-motion puppets of the Sesame Street Muppets are also included, designed and animated by L.A.-based Screen Novelties.

Trivia
The special's score and original songs were written and composed by Kurt Heinecke, who is best-known for his work on the children's video series VeggieTales. Heinecke opted to give the special a musical sound completely different from the usual Sesame fare, but one that would fit the tone of the special and its setting, with music influenced by Danny Elfman's scores for many of Tim Burton's films, the more intense works of Hans Zimmer and Michael Giacchino, and, occasionally, Heinecke's own music from VeggieTales. On a related note, Phil Vischer and Mike Nawrocki, the primary voice actors for VeggieTales, were credited as "additional voices" for the special.

For the scenes taking place in the Grandcount's castle, the crew took inspiration from Disney's "Haunted Mansion" attraction and films like Corpse Bride, Beetlejuice and The Rocky Horror Picture Show, as well as a nightmare sequence in the vein of the "pink elephants" scene from Disney's Dumbo and the "Heffalumps and Woozles" scene from The Many Adventures of Winnie the Pooh. Corpse Bride and Beetlejuice director Tim Burton, and Rocky Horror creator Richard O'Brien were actually credited as "creative consultants", as were R.L. Stine, author of the Goosebumps books, and composer Danny Elfman (a frequent collaborator of Tim Burton).

The Grandcount's castle contains recreations of the sets of both Family Feud and Jeopardy. The hosts of the shows, Steve Harvey and Alex Trebek respectively, make appearances as themselves.

Being a special celebrating Sesame Street's 50th anniversary, dozens of classic Muppets make cameos as ghosts in the Grandcount's castle. Lefty the Salesman, Sherlock Hemlock, Forgetful Jones and others make short, speaking cameos throughout the special, while Roosevelt Franklin and Deena appear as the ghosts of two of the children of Countess Ohanna's ex (played by Gonger) who were all murdered when Gonger tried to divorce her (the other two are played by Julia and Rudy).

Joey Mazzarino returns to perform Murray Monster in this special, with his name featured in the "Sesame Street Muppet Performers" credit.

This special marks Karen Prell's first performance on Sesame Street since 1981 (not counting the 2003 attraction Sesame Street 4-D Movie Magic), reprising her major role, retired character Deena Monster. The character was initially planned to be recast to Pam Arciero, until Prell offered to personally come to New York for two days to shoot the scenes featuring Deena. For her performance, Prell is given a "special appearance" billing during the end credits.

Though she doesn't puppeteer in this special, Julianne Buescher makes a vocal appearance as Loopy the ventriloquist's dummy (her actual puppetry was handled by Rachel Herrick). Louise Gold, another veteran Muppet performer, voices a giant vampire bat (operated by Jenifer Barnhart) in a deleted scene. Two other Muppet performers, Fran Brill and Bill Barretta, make on-screen cameos as zombies, as do fellow performers Tyler Bunch, Noel MacNeal and Martin P. Robinson, and longtime Henson director Kirk Thatcher.

Perhaps as a nod to the misconception of her ever appearing on Sesame Street, Miss Piggy makes her first (and so far, only) appearance in a Sesame production, alongside Kermit the Frog, known for his regular guest appearances on the show. In their cameo, Kermit and Piggy appear as dangling corpses in the Grandcount's castle. After Oscar runs away from them, Piggy abruptly animates, irritated about having to be on "a silly little kid show". Kermit rebuts that it's only a one-time appearance, "and besides, it pays well." Piggy, understanding but still annoyed, returns to being lifeless, with Kermit following almost immediately. Both Kermit and Piggy receive "special guest appearance" credits at the end.

The celebrity ghosts that haunt the graveyard adjacent to the castle are named after members of the original Sesame Street creative team: Jon (Stone), Jim (Henson), Chris (Cerf), Joan (Ganz Cooney), Tony (Geiss), Joe (Raposo), Cathi (Turow), Frank (Oz), Emily (Perl Kingsley), Lisa (Simon), Jeff (Moss), Caroly (Wilcox), (Jerry) Juhl, Dulcy (Singer), Judy (Freudberg), and Don (Sahlin).

Principal photography for this special took place between September 2018 and January 2019, with creature effects construction beginning in late May 2018, and post-production beginning in February. It was the final production that cameraman John Meiklejohn worked on before his death during post-production, and the special is dedicated in part to his memory.
