* Defining "famous": What constitutes "famous" is subjective. Is it based on awards, box office success, media attention, or something else?
* Counting Canadians: Accurately identifying Canadians in Hollywood is challenging, especially with dual citizenship or those who were born in Canada but became American citizens.
* Lack of comprehensive data: No official database exists that tracks the nationality of all Hollywood actors, directors, etc.
However, we can say that Canada has a significant presence in Hollywood. Many famous actors, directors, writers, and musicians are Canadian, and their contributions are well-recognized.
Here are some notable examples:
* Actors: Ryan Reynolds, Jim Carrey, Rachel McAdams, William Shatner, Eugene Levy, Dan Aykroyd, Michael J. Fox, Kiefer Sutherland
* Directors: James Cameron, David Cronenberg, Atom Egoyan, Guillermo del Toro
* Musicians: Justin Bieber, Drake, Celine Dion, Alanis Morissette, Bryan Adams
While a specific percentage can't be provided, it's clear that Canadian talent has a strong and lasting impact on the entertainment industry in Hollywood.
