How many films has Nicolas Cage appeared in?

How to get close to this number

Multiply career length by output rate. Four decades of work at a typical rate of one to two films a year would give fifty or so; this actor works considerably faster than typical, closer to three a year, which doubles it. Career length times annual rate is the reliable method for any filmography question.

The reason the rate is so high is explained rather than mysterious: a run of low-budget roles taken to clear tax debts. Career output is driven by economic circumstance at least as much as by choice, and an unusually long filmography usually has a financial explanation behind it rather than an artistic one.

Filmography counts are also definitional. Cameos, voice roles, direct-to-video releases, uncredited appearances and films that were shot but never released can each be counted or excluded, and different databases disagree by a dozen or more. Any figure for an actor with this volume of work should be read as approximate by construction.
