How can I learn more about the actors?

I am planning a massive movie marathon weekend with my friends, and we have decided to rewatch the entire Fast and Furious franchise from the very first film. While watching the trailers, we started discussing how much the main cast has changed over the last two decades. Some actors became global superstars, while others transitioned into directing and producing behind the scenes. I really want to find a reliable entertainment website where I can read detailed biographies and find out what the cast members are working on right now. Do you know any good movie blogs?
