He has been writing and podcasting about pop culture (especially horror movies) for over a decade at platforms including Blumhouse, Fangoria, Dread Central, The Backlot, and Arrow in the Head.

A look at Johnny Galecki's long-awaited return to acting after The Big Bang Theory has finally been revealed.

Galecki was a working actor long before he joined the Big Bang Theory cast in the lead role of Leonard Hofstadter, appearing in major movies and shows, including I Know What You Did Last Summer, Vanilla Sky, Roseanne, and The Opposite of Sex. He took on numerous other roles during the 12-season run of the smash-hit sitcom as well, appearing in titles such as Hancock, In Time, and Rings. However, he took a hiatus from acting once it went off the air in 2019, aside from providing a voice for the podcast miniseries The Cinnamon Bear: A Holiday Adventure.

Galecki made his return to non-voice acting in the fall of 2026, starring as iconic playwright Tennessee Williams in the stage play Kowalski, which was written by Gregg Ostrin and directed by Colin Hanlon and follows Williams meeting Marlon Brando (Jacob Moskovitz of Prime Video's Elle) before A Streetcar Named Desire premieres on Broadway. Ahead of the show's closure on November 8, Galecki shared a collection of his behind-the-scenes photographs from the production (which played at Chicago's Lookingglass Theatre) with PEOPLE.

Check out a selection of those photos, which include images of the set as well as Galecki both backstage and onstage with Moskovitz and their co-stars Reece Dos Santos (NBC's New Amsterdam), Alison Cimmet (The Big Sick), and Ellie Ricker (Y2K), below:

Johnny Galecki also posted a carousel of behind-the-scenes photos on his official Instagram account celebrating the closure of Kowalski, calling the show "an experience that will always remain a highlight of my life." Check out the post below:

While Galecki seems to have had a rewarding experience starring in Kowalski, it still remains to be seen if he will return to acting on either the big or small screens. So far, there have been no official announcements about any upcoming onscreen projects. However, he told PEOPLE that one reason he returned to acting was that he felt like "after seven years of quietly observing life, I finally had something new to bring back to the work."

If an onscreen project lights a similar spark in the actor, it seems possible that he could eventually find a new major role. This would see him following in the footsteps of many of his co-stars, who have taken on other iconic roles in the wake of the sitcom. This includes Kaley Cuoco (who was nominated for three Emmys for her HBO Max series The Flight Attendant) and Jim Parsons (who has taken roles in Spoiler Alert, Ryan Murphy's Hollywood, and The Boys in the Band).

However, it ultimately seems unlikely that Galecki will appear in further installments of the still-expanding The Big Bang Theory universe, as he has so far declined to appear in Young Sheldon (which featured narration from Simon Helberg - briefly - and Parsons, who also cameoed onscreen alongside Mayim Bialik), Georgie and Mandy's First Marriage, and Stuart Fails to Save the Universe (which has featured cameos from Cuoco, Bialik, Kunal Nayyar, and Melissa Rauch). While he has seemingly left his longest-running role behind, his return to acting may be the first project of many that relight his creative spark.
