Second City Chicago actor Sean Masterson wrote: "RIP Mike Hagerty. Funny, sweet and a total pro. Thanks for the decades of laughs."
Writer Will Harris said: "I’m extremely saddened to hear that Mike Hagerty has passed away. I wanted so badly to do a Random Roles with him for the AV Club, but even though he was a Chicago guy, the pitch was a no-go.
"Most depressing is that we were supposed to do an interview for my Substack newsletter when SOMEBODY SOMEWHERE premiered, but due to a scheduling issue, it never happened…and now it never will. #RIPMikeHagerty."
The Chicago Sun Times TV critic, Richard Roeper added: "Sad to hear of the passing of Second City stalwart and character actor Mike Hagerty, recently seen as the dad on Somebody Somewhere on HBO. Mike had the classic Chicago mustache and accent, and a natural onscreen presence. He always came to play."
