#Q ORIGINAL QUESTION

Regarding the film Alien: Romulus (2024), who was the most famous actor in it at the time of release, and what other notable films were they in?

#M ANNOTATED LLM RESPONSE

At the time of its release in August 2024, the most famous actor in Alien: Romulus was Cailee Spaeny, who starred as the film’s lead, Rain Carradine.

While the film intentionally cast a group of "rising stars" rather than established A-listers to maintain a sense of vulnerability, Spaeny entered the project during a massive "breakout year." However, Isabela Merced was also a strong contender for the title, having a longer history in major studio blockbusters.

1. Cailee Spaeny (The Lead)

By August 2024, Cailee Spaeny was widely considered one of Hollywood's most prestigious rising talents. She had just come off a critically acclaimed "it-girl" run that made her the face of the film’s marketing.

2. Isabela Merced (The Established Franchise Star)

If "fame" is measured by commercial name recognition and tenure in major franchises, Isabela Merced (who plays Kay) was arguably more well-known to general audiences at the time of release.

3. The "Legacy" Star: Ian Holm

A unique aspect of the film’s "fame" factor was the re-creation of the late Ian Holm. <span class='error-minor' data-annotation='3' data-tooltip='[Discrepancy: Missing Actor] While Holm's likeness was used, the actual performance (voice/face capture) was by Daniel Betts.'>Though he passed away in 2020, his likeness was used (via animatronics and CGI) to portray the android Rook, a model identical to his character "Ash" from the original 1979 Alien.

Summary of Other Notable Cast Members

#F CORRECTION FEED (CLICK TO SEARCH)

[1] Cailee Spaeny was indeed the top-billed lead and had achieved significant fame in 2023-2024 due to 'Priscilla' and 'Civil War'.
[2] Isabela Merced has a longer blockbuster resume ('Transformers', 'Dora') and is a valid contender for 'most famous' depending on the metric (prestige vs. commercial longevity).
[3] The character 'Rook' was a hybrid performance. While it used Ian Holm's likeness, the actual actor on set and providing the voice was Daniel Betts. The summary omits Betts entirely.

#O MISSED POINTS & OVERSIGHTS

Medium
Daniel Betts Performance

The summary attributes the character of Rook solely to Ian Holm's likeness and CGI/animatronics. It fails to mention Daniel Betts, the actor who provided the voice and facial capture performance.
