Michael Rosenbaum is still closely associated with Lex Luthor, but his career now stretches far beyond Smallville. The American actor has worked in film, animation, podcasting, directing, writing, and music. In 2026, his public work remains active through two established podcasts, his band Sun Spin, and continued ties to the Superman franchise.

The actor was born on July 11, 1972, making him 54 as of September 2026. He graduated from Western Kentucky University and built a screen career that began in the late 1990s. His credits later expanded from live-action roles into some of DC animation’s best-known series.
Best known for playing Lex Luthor on Smallville, Rosenbaum has built a broader career across film, animation, podcasting, and music. In 2026, he remains active through Inside of You, Talk Ville, and Sun Spin, while a proposed animated Smallville continuation still lacks a confirmed greenlight.
Why Michael Rosenbaum Is Still Closely Tied to Smallville
Smallville premiered in 2001 and followed Clark Kent before he became Superman. Rosenbaum played Lex Luthor through seven seasons, turning the character from Clark’s complicated friend into one of the show’s central antagonists. The performance earned him a Saturn Award for Best Supporting Actor in a Television Series in 2002, followed by several later nominations.
His version of Lex differed from portrayals that began with the character already established as a villain. The series gave viewers years to watch the friendship between Clark and Lex break down through ambition, secrecy, family conflict, and distrust. That longer arc helped the role remain a major part of his public identity long after he left the regular cast.
The connection has also stayed alive through reunions, convention appearances, and retrospective discussions. Fans interested in other television performers can also read this career profile of actor Alec Musser.
A Career That Goes Well Beyond Lex Luthor
Before and after Smallville, the actor appeared in films including Urban Legend, Sorority Boys, Bringing Down the House, and Hit & Run. Marvel audiences may recognize him as Martinex in Guardians of the Galaxy Vol. 2 and Guardians of the Galaxy Vol. 3. His credits also include the comedy series Impastor, where he played the lead role.
His voice-acting work is another major part of his résumé. He voiced Wally West, also known as the Flash, in Justice League and Justice League Unlimited, alongside additional animated DC roles. That work gave him a second long-running connection to superhero storytelling outside his live-action Lex performance.
That DC connection resurfaced in James Gunn’s Superman in 2025. DC confirmed that he voiced one of Lex Luthor’s Raptor soldiers, while the film’s credits identify the role as Raptor Guard #1. It was a small part, but it linked one of television’s best-known Lex actors to a new screen version of Superman.
Podcasting Has Become a Major Part of His Work
Inside of You has become one of his most visible projects outside of scripted acting. The interview podcast centers on long-form conversations with actors, musicians, athletes, and other public figures, focusing on personal experiences rather than standard promotional interviews. Its official site says new conversations arrive every Tuesday and lists more than 400 episodes.
The show remained active through 2026, with recent guests spanning film, television, and comedy. Podcast listings showed a Nick Frost episode dated September 1, 2026, following conversations with Patrick Renna, Sam Jones III, Kellan Lutz, and Nancy Cartwright. That continuing release schedule makes podcasting a current part of his career rather than a side project from the past.
He also co-hosts Talk Ville with Tom Welling. The series revisits Smallville episode by episode and adds production memories, guest appearances, and stories from the original set. September 2026 listings show the rewatch continuing into the ninth season, giving longtime viewers a direct connection to the people who made the series.
Sun Spin Adds Music to the Picture
Acting and podcasting are only part of his current creative work. He performs with guitarist Rob Danson in the band Sun Spin, contributing lead vocals, acoustic guitar, and lyrics. The group released its third album, Welcome to This Life, on December 5, 2025.
The 11-track record was recorded during 2025 in Los Angeles and at home studios. Blake Lewis contributed keyboards, production work, beats, and harmonies, while several other musicians joined the sessions. The project gives Rosenbaum a creative outlet that sits apart from the comic-book roles that first made him widely recognizable.

What Happened to the Smallville Animated Sequel?
Fans have heard about a possible animated continuation for several years. Rosenbaum and Tom Welling previously discussed developing a project that could bring back characters and members of the original cast. The idea also had support from the series’ creators, Alfred Gough and Miles Millar.
The project has not received a confirmed production order. In 2024, Welling said Warner Bros. had not given the team permission to proceed, and in March 2025 Gough said changes at the studio had put the idea aside for a while. No newer confirmed greenlight appeared in the current sources reviewed for this article.
That means fans should treat the animated continuation as an idea the creative team has wanted to pursue, not as an announced upcoming series. There is no verified release date, platform, episode count, or production schedule. Future statements from Warner Bros., DC Studios, or the original creators would be needed before its status changes.
Why His Career Still Has Several Audiences
One reason his work has remained visible is that different audiences know him from different periods. Smallville viewers associate him with Lex, animation fans know his Flash performance, Marvel viewers may remember Martinex, and podcast listeners encounter him primarily as an interviewer. His recent Superman voice cameo added another link between those parts of his career.
That range also helps explain why searches for him often produce more than a standard biography. People want older credits, current projects, podcast information, and updates about a possible return to the Smallville universe. A useful profile needs to cover both the career that built his reputation and the work he is doing now.
The Takeaway
Rosenbaum’s career is no longer defined by one television role, even though Lex Luthor remains the part most closely linked to his name. His active podcasts, recent DC cameo, music, voice work, and continued connection to Smallville give fans several reasons to keep following his work.
