Across 2999 TMDB films with valid financials, log-log OLS regression explains 65.2% of variance in box office revenue (R² = 0.652). The estimated budget elasticity is 0.461, meaning a 1% increase in production budget is associated with a 0.461% increase in revenue. Animation generates the highest median absolute revenue, while Horror delivers the strongest median return on investment.

The log-log scatter across 2999 films shows a clear positive relationship between production budget and box office revenue. The OLS slope (budget elasticity) is 0.461 — slightly below 1, indicating diminishing returns: doubling the budget does not quite double revenue. Genre coloring reveals that Action and Adventure films cluster at the high end, while Drama and Horror span a wide revenue range.

Median box office revenue varies substantially across 18 genres with at least 5 qualifying films. Animation leads with a median revenue of $246M. Genres with lower budgets (e.g., Horror, Documentary) tend to sit at the lower end of median revenue but may still offer attractive ROI — see the ROI by Genre card.

The OLS model (R² = 0.652) identifies log-budget as the dominant predictor with a coefficient of 0.461 — a 1% increase in budget predicts a 0.461% increase in revenue, holding other factors constant. Log vote_count and log popularity also contribute positively, capturing the combined effect of audience visibility and social buzz on commercial performance.

Median ROI (revenue / budget) differs considerably from median absolute revenue across 18 genres. Horror leads with a median ROI of 3.7x, meaning films in this genre typically return 3.7 times their production cost. High-budget genres like Action may have lower ROI despite higher absolute revenue, because their massive budgets eat into proportional returns.

The top 20 films by box office revenue are shown, led by Avatar with $2.79B in revenue. Note that ROI varies even among these blockbusters — high absolute revenue does not guarantee high ROI, as the largest-grossing films also tend to have the largest budgets. Primary genre is shown to identify whether certain genres dominate the top tier.

Across 2999 films, the Pearson correlation between audience vote average and log-revenue is 0.176. This weak-to-moderate relationship suggests that while better-rated films do tend to earn more, ratings alone are a poor predictor of box office success. Many commercially dominant blockbusters score 6–7 on vote average, while critically acclaimed films can underperform at the box office. Genre coloring shows that genre moderates this relationship.

Average box office revenue is shown across 51 release years (1961–2016) with at least 5 qualifying films each. 2016 produced the highest average revenue at $201M per film. The trend reflects a combination of industry growth, blockbuster cycles, and the increasing nominal scale of major studio productions over the decades.
