Thayne Jasperson, a key ensemble member and original cast member of Lin-Manuel Miranda’s hit show Hamilton, has been making headlines with his dedication to the musical. As one of the last remaining original cast members, Jasperson continues to shine as Samuel Seabury, a loyal British loyalist. Despite rumors that he would be leaving, Jasperson reassures fans that he will not throw away his shot.
Jasperson’s commitment to the show has been admirable, with Miranda praising his “incredible dedication” and work ethic. The actor finds creative fulfillment through side projects teaching or performing, such as a recent two-month run of an off-Broadway show. To keep the performance fresh, Jasperson tries small choices and improvisations, making Seabury both stoic and flamboyant.
Despite being over 45, Jasperson continues to perform eight shows a week, often biking to the theater for warm-ups. He maintains a rigorous lifestyle, including eating healthy and avoiding heavy snacks before performances. Jasperson credits his “mother-of-pearl” substitutions for more profane language, which helps him stay family-friendly.
Jasperson’s enthusiasm was palpable during an anniversary performance at the Tony Awards, where he reunited with past cast members. He expressed gratitude for the opportunity to continue making a difference in the show and vowed to never slack off, setting an example for newer cast members.
With his dedication and passion, Jasperson proves that it’s never too late to pursue your dreams and make an impact. As Miranda said, “Thayne, it’s okay. You can stay at the Richard Rodgers for as long or as short as you want, as long as you still love coming to work.”
