I Watched The Documentary That 'Song Sung Blue' Is Based On, And It Made Me Appreciate One Character Even More

I might declare "Sung Song Blue" the best movie I didn’t see coming this year. Despite looking forward to almost every music biopic, music documentary, and music-based TV show in a given year, this one wasn’t really even on my radar until a couple of weeks before I caught it at the tail end of 2025, before looking ahead to the 2026 movie schedule

I really liked the movie about a Neil Diamond tribute act called Lightning and Thunder, played by Hugh Jackman and Kate Hudson, respectively. One character that I really love is Thunder’s mother, played by Cecelia Riddett. Grandma Stengl, as she’s referred to in the movie, stole every scene she was in, and that’s not the half of it. After watching the documentary that the movie is based on, I love her even more.
