* Data is inconsistent: There isn't a single, comprehensive database that accurately tracks every movie appearance by every actor.
* Definitions vary: What counts as a "movie"? Short films, documentaries, voice roles, cameos? These all factor in.
* Uncredited roles: Many actors have uncredited appearances that may not be widely documented.
However, some of the actors consistently appearing on lists of those with the most film credits include:
* Christopher Lee: Renowned for his villainous roles, he is often cited as having starred in over 200 films.
* Donald Pleasence: Known for his roles in horror films, he also has a long and varied filmography.
* Eric Roberts: A prolific actor with hundreds of film credits, he's also known for his younger brother, Julia Roberts.
It's important to remember that these lists are estimates, and the true number of films a star has been in is often difficult to ascertain.
