Anyways, I had so much fun looking at this data (and still had the formula primed and ready in Excel) that I decided to make a follow-up. The winner of the raffle: Johnny Depp.
Addendum (7/7/16): I recently saw a post on reddit talking about a downturn in Robert De Niro's film career. I of course immediately thought this was a perfect opportunity to make another one of these charts. So, Robert De Niro it is:
(1) He obviously had movies before Mean Streets in 1973. I didn't include these both because they often didn't have very publicized budgets and/or profits and because the movie's reception likely didn't have much to do with him specifically. But once he got recognized as a lead actor, man what a start he had. Back-to-back movies of Mean Streets, The Godfather Part II, and Taxi Driver all earning massive amounts of money (a minimum of 400% of its budget) and receiving amazing reception from both critics and audience members (a minimum of an 8-out-of-10).
(2) In contrast to that original reddit post that was citing 2002 as "the year Robert De Niro stopped caring," this chart shows that since 2010's Machete De Niro has had a much higher frequency of movies that have made more than their budget - specifically even in the 500% range on average. Over his whole career, there's definitely a slight downward trend in his ratings, but even these ratings of the past 5-10 years still have high and low spikes that mostly fit in line with the rest of his career.
(3) Overall, there were a surprisingly high number of movies that made less than their budget. Definitely more than I expected. But on top of that, especially in the span of 1976-2008 (bookended on this chart by The Last Tycoon and What Just Happened?), there seems to be these rhythmic chunks that spike up in box office earnings. The Deer Hunter, The Untouchables, Cape Fear, Jackie Brown, Meet the Parents, and Meet the Fockers all seem to stand out from their surrounding movies and they're all roughly an even 7 movies away from each other.
