Why doesn't Frank Oz perform with the Muppets anymore?

Frank Oz was one of Jim Henson's closest creative partners, beginning in 1963. Oz played Bert to Henson's Ernie on Sesame Street, and he also performed Cookie Monster and Grover. In 1976, Oz created many of the core characters for The Muppet Show, including Miss Piggy, Fozzie Bear, Animal and Sam the Eagle, and he continued to perform these characters in the Muppet movies and TV specials. Henson and Oz collaborated on the 1982 film The Dark Crystal, directing as a team.

In the mid-1980s, Henson and Oz began to pursue separate creative projects, outside of the Muppets. Henson produced fantasy film and television projects -- Labyrinth (1986), The StoryTeller (1988) and The Witches (1990). Meanwhile, Oz began a career of directing comedy films -- Little Shop of Horrors (1986), Dirty Rotten Scoundrels (1988) and What About Bob? (1991).

In 1989, Henson created a new Muppet TV series, The Jim Henson Hour, with "MuppeTelevision" segments filmed in a studio in Toronto. Oz, who was working on film projects at the time, participated in the show by filming solo segments with Fozzie Bear and Miss Piggy. Fozzie was seen in New York City in episode 103, and Oz performed both Miss Piggy and Fozzie for "Miss Piggy's Hollywood", a half-hour segment in episode 105.

When Henson died in 1990, and his children began to run the Jim Henson Company, Oz began a gradual process of pulling away from performing Muppet characters, and focusing on his directing career.

In a 2007 interview, Oz explained why he distanced himself from the Muppets:

"I had done this for 30 years, and I had never wanted to be a puppeteer in the first place. I wanted to be a journalist, and really what I wanted to do was direct theatre and direct movies. As an actor and a performer, you feel limited because you're not the source for the creation, and I wanted to be the source... I've always enjoyed, more than anything else, bringing things to life, whether it be characters or actors in a scene or moments in movies. I've done so much with puppets, that I've wanted to work with actors."

1990s Muppet projects
After Jim Henson's death, his 27-year-old son Brian was named President, Chairman and CEO of the Jim Henson Company. Brian planned to revive the Muppet franchise with a series of movies, beginning with the 1992 film The Muppet Christmas Carol. Oz was working on another movie at the time, but supported the Muppet project by performing Miss Piggy, Fozzie Bear, Animal and Sam the Eagle in several scenes.

The Muppet Christmas Carol gag reel includes a sly reference to Oz's limited time on the set. In one scene, Gonzo and Rizzo the Rat (performed by Dave Goelz and Steve Whitmire) are sitting on a shelf next to a bust of William Shakespeare. Noticing a resemblance to Oz's hairline, Rizzo says, "Hey, it's Frank Oz!" Gonzo says, "Whoa, they've coated him with plaster!" and tries to get "Frank's" attention: "Frank, speak to us!" "Huh," Rizzo says, shaking his head. "As usual." The laughter that can be heard on this clip indicates that Goelz and Whitmire were expressing a feeling shared by many on the set.

In 1996, Oz was unable to participate in the filming of Muppet Treasure Island at all, because he was directing Bowfinger. Kevin Clash performed Oz's characters on set, and Oz looped the dialogue in post-production.

For the 1996 TV show Muppets Tonight, Oz performed Miss Piggy, Fozzie and Sam the Eagle in a limited number of episodes. Miss Piggy appeared with many of the guest stars, including Michelle Pfeiffer (episode 101), Garth Brooks (episode 102), Billy Crystal (episode 103), Whoopi Goldberg (episode 109) Martin Short (episode 110) and Pierce Brosnan (produced in the first season, but aired as Episode 204). Oz involvement was even more limited in the show's second season.

For the 1999 film Muppets From Space, Peter Linz performed Oz's characters on set, and again Oz looped the dialogue in post-production.

Sesame Street
Sesame Street puppeteer Eric Jacobson started performing Bert in 1997 on a semi-regular basis, and the next season he started performing Grover as well, due to his strong puppeteer talent and extremely similar vocal-range. (Veteran Muppet performer David Rudman took over the role of Cookie Monster in 2001).

As Oz later stated: "Eric Jacobson and those guys have been very respectful, they've done a great job, and I'm just pleased that they're there."

Oz continues to return to Sesame Street to perform Grover and other characters from time to time; including Grover in Elmo's Potty Time (2006), Grover as a Russian restaurant waiter (2006), Mr. Draper in a Mad Men parody (2009), Keith Heartburn in a Deadliest Catch parody (2011), and Grover as Spider-Monster (2011).

Departure from the Muppets


In the early 2000s, Oz retired from performing Miss Piggy, Fozzie Bear, Animal, and Sam the Eagle.

In December 2001, Eric Jacobson secretly debuted as Miss Piggy's new performer in a video greeting shown at the MuppetFest fan convention. Jacobson made his first major Muppet production debut performing Fozzie Bear, Miss Piggy, and Animal in the 2002 TV-movie It's A Very Merry Muppet Christmas Movie. Jacobson took over the role of Sam the Eagle starting in 2005 with The Muppets' Wizard of Oz.

Oz's last known performance of Miss Piggy was on January 14, 2002, alongside Kermit the Frog as part of the 50th anniversary celebration of NBC's Today.

The Muppets
Evidently, Frank Oz was offered the chance to perform in the film The Muppets, despite the fact that as noted, he had retired from Muppet performing. In Fall 2011, when speaking of the early script of the then upcoming film, Oz was quoted in a UK article as saying:

"I turned it down, I wasn’t happy with the script. I don’t think they respected the characters. But I don’t want to go on about it like a sourpuss and hurt the movie."

Oz stated in the same interview that:

"Working with Jim and the Muppets was very exciting... I feel so deeply privileged to be part of it. But when you work for 30 years on something, you wanna do something else."

Oz's quote about being dissatisfied with the movie's early script was soon publicized, picked up by several U.S. websites and bloggers, combined with unsourced claims that some of the film's Muppet performers were also unhappy with the movie. Since Oz's Muppet retirement in 2000 was relatively quiet, some of these authors were under the impression that his dislike of the early script was the reason for his departure from the Muppets, even though his true departure from performing with the Muppets was almost ten years prior.
