This selection of quotes was painstakingly compiled over a period of more than a year by several generations of regulars at the Keanu Reeves IMDb boards. Since then, I've expanded this selection while going through articles and interviews.
Someone once accused us of making them up, but well, all those quotes have names attached, and most of the interviews in question can be found in our Articles Archive, so just go look for yourself. It is true that some of those articles are not available online; however all our sources are legit as far as we know. We do have some basic level of honesty.
These quotes come from a variety of sources, including magazines, television interviews, DVD special features interviews, newspaper articles, online blogs, and so on.
(With many thanks to LucaM for tracking down the first lot of quote sources.)
