Source: TMDB. Domestic/international split (~34/66, genre-typical) and the opening-weekend figure (37% of the domestic run, typical for Science Fiction) are MoviesRankd estimates. Profit is gross revenue minus production budget and excludes marketing — studios typically need ~2–2.5× budget to break even.
