The FLCL: Grunge anime premiered on Saturday within Adult Swim’s Toonami lineup, unveiling its English dub cast. Notably, this cast features Samantha Weinstein in her posthumous anime dub debut. Weinstein’s contributions encompassed additional voices, with her portrayal of Akira in the anime being a standout.

Tragically, Weinstein, who was only 28 years old, succumbed to ovarian cancer on May 14. This remarkable talent, born in March 1995, left her mark not only in the anime world but also in the realm of film, having appeared in works such as Carrie and Toronto Stories.
