The Muppets Twitter account has recently revealed a first look poster of late veteran actor Ed Asner, who is set to make his final on-screen appearance via a cameo in the upcoming original Halloween special, Muppets Haunted Mansion, premiering on Disney+ October 8.

Although the post confirms that the special will see many guest star cameos ”to be revealed soon,” this one sure pulls on the heart and is easily the most exciting. Asner recently passed away in late August and was a “great friend of the Muppets.” While the post is unclear whether the actor will be portrayed as himself or otherwise, simply having The Mary Tyler Moore Show actor back on screen in any capacity will be a definite treat for fans.

Asner is an Emmy award-winning actor most prominently known for playing Lou Grant in The Mary Tyler Moore Show and soon after his spin-off Lou Grant series. He is also seen in films such as 2009s Pixar's Up, where he played Carl Fredricksen, and portrayed Santa Clause in 2003s Elf. The actor has racked up an impressive resume and become one of T.V and film's biggest names. He will also make other posthumous guest appearances later this year in projects such as the Premise, Scarlett, Awaken, The Last Saturday Night, A Fargo Christmas Story, and Back Home Again, as well as upcoming documentaries The Gettysburg Address, Sills and Stu's Show, and Corsi: The World's First Supermodel.
