Jake Gyllenhaal plays Mr. Music

In John Mulaney & the Sack Lunch Bunch, Gyllenhaal plays an eccentric character named Mr. Music. He performs the song “Music, Music Everywhere!” and tries to teach kids about the power of music.

Throughout the song, Gyllenhaal’s character becomes increasingly unhinged. As he loses it, one of the children asks Mulaney if he is okay.

“No, Mr. Music’s not OK. He’s having a lot of trouble,” Mulaney says.

Viewers were wowed by Jake Gyllenhaal’s performance

It seems casting Gyllenhaal as Mr. Music was a perfect choice. Not only did Gyllenhaal appear to have fun with the role, viewers of John Mulaney & the Sack Lunch Bunch loved the cameo as it was both frightening and spectacular.

“jake gyllenhaal as mr. music genuinely one of the most frightening things i’ve seen,” a Twitter user wrote.

“I can’t believe we managed to fit in Jake Gyllenhaal as Mr. Music before the decade ended. As always, thank you John Mulaney,” tweeted a fan.

“Jake Gyllenhaal’s Mr. Music character is just an unofficial origin story for Mysterio,” wrote a Twitter user.

Several other celebrities had cameos in ‘John Mulaney & the Sack Lunch Bunch’

Mulaney’s music special has 10 musical numbers. Eli Bolin composed the music and Mulaney and Marika Sawyer wrote the lyrics. Including Gyllenhaal, there are six celebrity cameos. Richard Kind, André De Shields, David Byrne, Natasha Lyonne, Annaleigh Ashford all make appearances in John Mulaney & the Sack Lunch Bunch.

De Shields is a Broadway veteran, and in the special he performs the song “Algebra Song!” Lyonne is no stranger to Netflix shows and fans know her from her roles in Orange is the New Black and Russian Doll. In the special, Lyonne makes an appearance as herself.

Like De Shields, Ashford is also a Broadway legend and plays a crying woman on the streets of New York City. Kind makes an appearance as himself in a segment called “Girl Talk With Richard Kind.”

Byrne sings a song called “Pay Attention!” in a sketch when one of the children in the cast cannot get parents in the audience to pay attention to her performance. Mulaney was apparently surprised Byrne was willing to take part in the special.

“David Byrne, one, picked up the phone when I called, and two, agreed to be on,” Mulaney told EW. “His yes was the first time I ever thought, ‘I think this could work, I have no way to describe it to anyone. But I can picture it and I can see it in my head.'”

‘John Mulaney & the Sack Lunch Bunch’ earned rave reviews

Currently, John Mulaney & the Sack Lunch Bunch has a 100 percent critic score on Rotten Tomatoes. The special has received universal acclaim. While this is not surprising considering it’s Mulaney’s project, it is surprising because the Netflix special succeeds at being both a parody and taking itself seriously.

“Talk about taking risks. In lesser hands, the premise of this Netflix comedy special could have resulted in an epic fail — a career-stalling stumble. Mulaney is far too good to let that happen,” wrote Richard Roeper in the Chicago Sun-Times.
