Comedy, stunts and character work
A Chicago-trained performer working across stage and screen.
From improvisation to a horror ensemble
Shaun W. Loeser is an actor and stunt performer whose work spans screen productions and live comedy. The cast biography for Santasia describes his Chicago roots and training in improvisation at iO Chicago with Del Close.
Loeser also works on Santasia, a holiday comedy production, as a performer, director, producer and co-writer. That work brings together the collaborative disciplines of stage performance and creating material for an ensemble.
His screen credits include Step Brothers and television work, while the cast list for the 2026 Resident Evil credits him as Puker. His performance belongs to a horror ensemble rather than the comedy setting of his stage work.
The film links below are drawn from the FLM.RED database and show only the titles available on the site, not a complete list of his work.
