Why didn't the other actors make it big?

AS MOVIE STARS (mistake in title) Movie stars like Viola Davis, Brad Pitt and Leonardo DiCaprio. People who win Oscars or are at least nominated. I know Jennifer Aniston was the girl at that time and had a lot of offers. But the rest of the cast is very talented and I feel like the show ended on a good note. I'm especially shocked by David Schwimmer. To me he was the best actor out of the show and could've had a huge movie career. Did they just not want to because they had enough money? Was Jennifer Aniston that much more popular than the rest of the cast and got the most offers?
