What Happened to Johnny Galecki? Here’s What the ‘Big Bang Theory’ Star Is Doing Now
For 12 seasons, Johnny Galecki played Leonard Hofstadter in ‘The Big Bang Theory’, and when the CBS sitcom ended in 2019, he largely stepped away from the spotlight. That’s why his return to acting on stage became one of the more unexpected comebacks of the year. The fact that it happened in a theater in Chicago, not in front of TV cameras, made it even more unusual.
Galecki came to fame in the 1990s on ‘Roseanne’, but his roots are in the theater. He started performing on local Chicago stages as a child, and he won a Theatre World Award for his Broadway turn in ‘The Little Dog Laughed’. After ‘The Big Bang Theory’, he moved from Los Angeles to Nashville, married his wife Morgan and quietly welcomed 2 children.
Now that chapter has come full circle. The 51-year-old actor has wrapped his run as Tennessee Williams in ‘Kowalski’ at Chicago’s Lookingglass Theatre Company, and to mark the end of the production, he shared a set of behind-the-scenes photos with fans. It’s a fitting send-off for a role that pulled him out of a seven-year break from acting.
Written by Gregg Ostrin, ‘Kowalski’ imagines the first meeting between Tennessee Williams and a young Marlon Brando. It takes place over a single evening in Provincetown in 1947, while Williams is searching for the actor who will play Stanley Kowalski in ‘A Streetcar Named Desire’.
The play blends real history with invented scenes to explore ambition, artistry and the collaboration behind one of America’s most famous dramas. Jacob Moskovitz played Brando opposite Galecki, and the cast also included Alison Cimmet as Margo Jones, Reece Dos Santos as Pancho and Ellie Ricker as Jo.
Colin Hanlon, who directed the play’s Off-Broadway production in 2025, returned to direct the Chicago premiere at the historic Water Tower Water Works. The run was originally scheduled from mid-September to late October, but Lookingglass extended it into November.
Galecki announced the role on Instagram in July. He explained that he had spent the past several years focused more on living than on performing, and he called it an honor to return to the stage in his “city by the lake,” where his career began.
In a statement about the production, he said everything simply came together. He credited Ostrin’s writing and Hanlon’s vision, and added that the chance to play one of his artistic heroes made the offer impossible to turn down.
The news got plenty of attention online, especially from longtime fans who had wondered whether the actor would ever act again. Many had expected a TV return, so seeing him choose a dramatic stage role was a surprise.

The reviews were largely kind to the star. The Lookingglass Theatre page highlights Chicago Tribune critic Chris Jones calling Galecki a revelation in the role, and other local reviewers described his chemistry with Moskovitz as magnetic.
New City Stage praised Galecki’s riveting, star-turn performance, saying he paints an indelible portrait of Williams as a complicated man while fully leaning into the playwright’s exaggerated Southern gentleman persona. It called the production a generally absorbing, well-acted drama.
Not everyone was won over by the play itself. The Chicago Sun-Times review argued that the script lacks the poetry and rawness of Williams’ own work, though it noted that the cast avoids playing their famous characters as straight impersonations.
Galecki hasn’t announced any acting projects beyond ‘Kowalski’, so it’s unclear whether this was a one-time return or the start of a new chapter. For now, the behind-the-scenes photos give fans a closer look at a production that clearly meant a lot to him.
For an actor known to millions as a lovable physicist, playing one of America’s greatest playwrights in his hometown was a bold way to step back into the spotlight. It’s also a reminder that the stage was always where his story began.
