The default Known For titles displayed at the top of an individual's IMDb page are automatically chosen through a complex weighting system.
IMDbPro members may choose which titles appear in their Known For section.
Every credit in the filmography is assigned a "weight" based on a series of factors. These may include:
These aren't the only factors we consider, but should be enough to give an idea of the approach we've used. The top four titles with the highest score are listed in the 'Known For' category.
The algorithm used to select Known For titles is constantly being improved. Also, the weight assigned to each title within a filmography is recalculated on a periodic basis, so the addition of new credits on someone's filmography will have an impact on their Known For titles.
Since this is an entirely mathematical approach, some of our Known For choices may occasionally not be the best or most representative ones - if you're an active IMDbPro member, you may select your Known For titles.
