“It’s a good thing… a REAL good thing” we did! We’re excited to welcome the one and only Bill Mumy to Retro Con 2026 for a rare east coast convention appearance! With a career spanning the golden age of television, genre-defining sci-fi, and an eclectic music career, Bill Mumy is a true multi-talented entertainer whose work has captivated fans for decades!

Fans of the Twilight Zone will instantly recognize Bill as the all-powerful and disturbing six year-old Anthony Fremont in the iconic episode “It’s a Good Life”. Often ranked among the greatest episodes in television history, its legacy proved so strong that Bill returned to the role four decades later in a 2003 sequel episode “It’s Still a Good Life”. So be good, smile, and think happy thoughts… or else it’s off to the cornfield with you!

“Danger, Will Robinson! Danger!” And of course sci-fi fans know Bill most as pop culture icon Will Robinson from the classic 1960’s TV series ‘Lost in Space’! As the youngest member of the Jupiter 2 crew, Will became the emotional heart of the series- Brave, curious, and always at the center of the adventure. His friendship with the Robot, and his unforgettable back-and-forth with Dr. Smith, created some of the most enduring moments in sci-fi history.

In the 1990s, Bill returned to the genre in a completely different way as Minbari aide Lennier on Babylon 5. Quiet, thoughtful, and deeply loyal, Lennier’s journey added emotional depth and complexity to the series, proving Bill’s remarkable range as an actor.

And beyond acting, Bill’s musical career is just as impressive! His latest acoustic album “Will Power” just dropped in March 2026, he has collaborated with the band ‘America’ for over thirty years, and continues to perform as part of the rock trio ‘Action Skulls’. And fans of offbeat tunes will also know him as one half of ‘Barnes & Barnes’, the infamous duo behind the bizarre cult hit “Fish Heads”! This earworm of a song premiered in 1978 and became the most requested song of all time on The Dr. Demento Show!

This is an extremely rare East Coast appearance for Bill Mumy, his first in the region since 2018, and his only scheduled appearance on this coast! So don’t miss your chance to meet a true legend of television, sci-fi, and music at Retro Con 2026!!

Bonus: Bill will also be performing a limited-ticket concert in our panel room on Saturday evening after Retro Con has closed for the day! This special concert is being handled by his event agent, and you can find more details here:
