Sebastian Sero Actor Credits: Anaconda and The Clearing
Sebastian Sero’s screen credits include a Hollywood comedy, an Australian television thriller and a musical biographical film. His work also extends to English-language voice performances, although those credits should be distinguished from appearances in front of the camera.
Sebastian Sero as Charlie in Anaconda (2025)
Sero plays Charlie in Anaconda, the 2025 comedy starring Jack Black and Paul Rudd. The film follows Doug McCallister (Black) and Ronald “Griff” Griffen Jr. (Rudd), two longtime friends who set out to make a movie inspired by their favorite childhood film.
According to Sony Pictures’ official synopsis, the 2025 production is an original comedy inspired by the earlier Anaconda. It is therefore more accurate to describe it as a new take on the premise than as a straightforward remake of the 1997 film.
Cast records identify Sebastian’s role as Charlie. The production is one of his most recognizable screen credits, although his participation should not be confused with the leading roles played by Black and Rudd.
His role as Aaron in The Clearing (2023)
Before Anaconda, Sero appeared as Aaron in The Clearing, an Australian psychological-thriller miniseries released in 2023. The production stars Teresa Palmer, Miranda Otto and Guy Pearce.
The series follows a woman whose memories of a dangerous cult resurface after a child disappears. Sero is credited as Aaron in filmography records, while the show’s principal promotional materials focus mainly on its leading cast.
The Clearing was an earlier television credit for Sero. It also placed him in a production quite different in tone from the musical-theatre shows in which he had performed.
Sebastian Sero in Better Man (2024)
Sero also has a credit in Better Man, the biographical musical film about British singer Robbie Williams. Released in 2024, the film was directed by Michael Gracey.
His credited involvement is as part of the children’s theatre ensemble. That is an ensemble credit rather than a named leading character, a distinction worth preserving when describing his film career.
Sebastian Sero Movies and TV Shows
Sero’s selected filmography includes acting, ensemble and English-language voice credits. These are different forms of performance, so a single list without role descriptions can give an incomplete impression of his work.
| Production | Year | Role or Credit |
|---|---|---|
| The Clearing | 2023 | Aaron |
| Better Man | 2024 | Children’s theatre ensemble |
| The Shadow Strays | 2024 | Moji (English-language voice credit) |
| Anaconda | 2025 | Charlie |
| Delusion | Listed as 2026 | Young Watt |
| The Fixers | Listed as 2026 | Howie |
The table contains selected database credits rather than a certified complete filmography. In particular, the 2026 entries are listed in Plex’s filmography records; those listings alone do not establish every production’s release status or availability in a particular country.
Sero is also associated with Magic Beach, directed by Robert Connolly. Some filmography services categorize this under appearances rather than assigning him a named fictional character, so it should not automatically be counted in the same way as his roles in Anaconda or The Clearing.
How Old Is Sebastian Sero?
Sebastian Sero was born on July 13, 2012, making him 14 years old as of October 23, 2026. His birth date appears in a specialist Billy Elliot performance archive, which identifies his age when he first played the musical’s title character.
He is associated with Melbourne’s performing-arts community. A May 2024 report in Star Weekly described Sebastian and his younger brother Luka as performers from Williamstown, Victoria.
However, being associated with Williamstown or Melbourne does not confirm his precise place of birth. No sufficiently reliable source reviewed for this biography establishes an exact birthplace.
Sebastian Sero’s Early Acting and Musical-Theatre Career
Long before his appearance in Anaconda, Sero had performed in several Australian stage productions. His theatre credits include musicals that required singing, acting and carefully rehearsed live performances.
The Billy Elliot performance archive documents his early roles, including Young Tommy in Victorian Opera’s The Who’s Tommy (2021) and John Bechdel in Fun Home (2022).
He later performed as Michael Banks during the Australian tour of Mary Poppins in 2023. His other reported stage credits include Young Elvis in Elvis: A Musical Revolution and Bronson in Round the Twist during 2024.
These productions provide useful context for his acting experience. A filmography focused only on screen credits would miss several years of documented performance work.
Sebastian Sero as Billy Elliot
One of Sero’s best-documented theatre roles is the title character in Billy Elliot the Musical. He first performed as Billy on May 10, 2024, in a Melbourne production presented by CLOC Musical Theatre.
He returned to the role in a separate Geelong production during January and February 2025. The specialist theatre archive records 15 performances across the two productions, including six in Melbourne and nine in Geelong.
His final listed Geelong performance took place on February 2, 2025. The documented dates make Billy Elliot particularly useful for understanding the stage work he completed before his wider exposure through Anaconda.
A contemporary Star Weekly report also discussed Sebastian and Luka’s stage activities while Sebastian was appearing in Billy Elliot. It provides additional context for the brothers’ involvement in Australian theatre.
Sebastian Sero’s Voice Acting Work
Sero’s performance credits extend to English-language dubbing. The theatre archive identifies voice work associated with The Shadow Strays, Terror Tuesday and Borderless Fog, while Plex specifically lists him as Moji in The Shadow Strays.
English-language dubbing involves recording dialogue for a version of a production intended for another language audience. A dubbing credit does not necessarily mean the performer appeared physically in the original production.
This distinction is useful when comparing Sero’s voice performances with his on-camera work. His screen and dubbing credits demonstrate different types of involvement, but the available records do not justify treating every project as a leading acting role.
Sebastian Sero’s 2026 AACTA Young Stars Recognition
In 2026, Sebastian Sero was selected as the recipient of the AACTA Young Stars: National Youth Casting Call. The program gives emerging Australian performers opportunities to connect with casting professionals and receive career-development support.
The official AACTA announcement confirms his selection. It also describes a development package that includes professional training opportunities, industry connections and travel-related support.
The recognition has a specific meaning: Sero was chosen through a national youth casting initiative. It was not an AACTA Best Actor award or a prize for his performance in Anaconda.
His selection is relevant to coverage of rising actors to watch, particularly because the initiative focuses on young performers developing professional screen careers. Still, the verified achievement is his selection as the 2026 Young Stars recipient, rather than a prediction about future fame.
Sebastian Sero’s Family and Music Career with Luka Sero
Sebastian Sero also performs music with his younger brother, Luka Sero. Together, they are known as the Sero Brothers, a Melbourne-based pop-rock duo.
Their music project runs alongside their individual acting careers. Both brothers have experience in Australian musical theatre, while their recordings allow them to perform original songs outside stage productions.
The brothers’ Triple J Unearthed artist profile identifies Sebastian as a vocalist and guitarist and Luka as a vocalist and drummer. The page includes music such as Brother, Walk On, Bye! and Better Like This.
Their work as the Sero Brothers is separate from Sebastian’s screen credits, but it helps explain his continued involvement in singing and live performance. His publicly documented career includes both acting and music, with his stage background connecting the two.
