Billing
Counts from TMDB across their full career, self appearances out; a title counts in every role they held on it. The ring is the typical Midcredits score (the median percentile) of the role's titles that are on MovieCove, shown from 5 scored. Billing is TMDB cast order for roles with 25+ votes, billed in the top 30; the columns are the share of top-billed roles in each era, 5-year spans from the year on the label, merged until each holds at least 5 roles.

Percentiles are each film's standing among all films on MovieCove; the typical film is the median, so one outlier cannot drag it. Percentiles and reviewer scores count the films IMDb credits them on, for now; the Midcredits score bands, the shape of the crowd and the two cards count their MovieCove titles, shows included (a show ranked among shows), appearances as themselves left out. A descriptor is the shape of a title's IMDb rating distribution against the catalog; "most divisive" needs a spread wider than half of all titles, and a card names only a principal credit: a craft role, and on a show a crew role or a run of episodes, never a courtesy credit or a one-off guest spot.
Is James Callis' work okay for kids?
Across up to 9 MovieCove titles with content scores, sex & nudity, profanity and alcohol & drugs run heavier than most films.
Severity 0–100 from the Content Guide. Categories with under 10 votes on a title are not counted. The band's colour is the severity of their median, named beside it.
