Creator Michael Schur and star Charlie Day are publicly aligning their hopes for a season 3 cameo that would bring Day onto the Netflix comedy headlined by his wife, Mary Elizabeth Ellis.
The Campaign for a Cameo
Day floated the idea to News Of Los Angeles last summer, saying he would “love to be on her show” and was “keep[ing] my fingers crossed for a third” season. Schur, speaking at PaleyFest 2025, claimed ignorance until reporters relayed the quote.

He quickly added the pitch to his wish list: “Of course, I would love it … consider it on the docket for a theoretical season 3.”
Inside the Show’s Family Ties
- Ellis plays Emily, daughter of Ted Danson‘s retiree-sleuth Charles Nieuwendyk
- Season 2, now streaming, also features Danson’s real-life spouse Mary Steenburgen as both love interest and music professor
- Day and Ellis have shared the screen on It’s Always Sunny since 2005 and married since 2006
Day praised the spotlight the series gives his wife: “Everyone knows her from Sunny … but she’s been in all these great things, like Licorice Pizza, and she’s incredible in that.”
Key Takeaways
- Netflix has not yet renewed A Man on the Inside for season 3
- Both Schur and Day are openly enthusiastic about a cameo if renewal happens
- The potential casting would add another real-life couple to a show already leaning into family dynamics

Should Netflix green-light another chapter, viewers might soon see Charlie Day cracking cases-or jokes-alongside Mary Elizabeth Ellis on A Man on the Inside.
