Matilda Firth Briefly Listed on Avengers: Doomsday as ‘Little Girl’

Overview

• Entertainment outlets reported that Matilda Firth’s talent agency briefly listed her on Friday as part of Avengers: Doomsday under the generic credit “Little Girl,” and the listing was removed from the public page shortly after.
• Marvel Studios has not confirmed Firth’s casting and the agency page is the only public source linking her to the film, so the report remains unverified.
• The generic credit and its removal have prompted fan theories that the part could be a simple civilian cameo or a masked reveal such as a younger version or relative of an established character, and those possibilities are speculative at this stage.
• Avengers: Doomsday is already billed as a large Multiverse Saga crossover with confirmed returns by several MCU and legacy actors and reported additions like the Fantastic Four and expected Thunderbolts appearances, which helps explain why Marvel tightly controls casting details.
• Marvel’s past practice of using vague or fake credits to protect plot surprises means the brief listing will likely increase scrutiny of future casting pages and could fuel more guarded marketing and spoiler management as the film finalizes its ensemble.
