Christopher Carroll is an American actor recognized for his extensive body of work in English-language dubs of anime series and films, often credited under the professional pseudonym Sam Strong. His career as a voice artist was particularly active during the 1990s and early 2000s, coinciding with a formative period for the English-language anime localization industry in North America.

Carrolls voice work is closely associated with prominent dubbing studios of that era, including Animaze and ZRO Limit Productions. These studios were responsible for producing English adaptations for numerous influential titles, and Carroll, whether under his own name or as Sam Strong, contributed to a wide breadth of projects. His filmography includes supporting and character roles in a diverse range of genres, far beyond a single series or character type.

Among his credited roles, Carroll provided the voice for Dr. Komyoji, the creator of the titular android, in the series Android Kikaider: The Animation. He also voiced the character Guren, one of the twelve shikigami in service to Abe no Seimei, in the supernatural series Shonen Onmyouji. His other significant anime credits include the role of Daido in the critically acclaimed cyberpunk series Ghost in the Shell: Stand Alone Complex and its second season. He also lent his voice to projects such as Cowboy Bebop, Trigun, the Animaze-produced English dub of the landmark film Akira, as well as Perfect Blue, Mobile Suit Gundam: The Movie Trilogy, El-Hazard: The Magnificent World, Armitage III, and Battle Fairy Yukikaze.

Throughout his voice-over career, Carroll frequently collaborated with a consistent circle of voice actors, a common characteristic of the close-knit dubbing community at the time. He worked alongside performers such as Mona Marshall, Barbara Goodson, Bob Papenbrook, and Kirk Thornton on multiple projects. In addition to his animation work, Carroll maintained an active career in live-action film and television, with guest roles in series that include The Fresh Prince of Bel-Air, Boston Legal, Desperate Housewives, and Mad Men, as well as a film role in Little Nicky.
