Lem is best known for Solaris, of which there are two film adaptations. imho the book is better than both films, and the first film is better than the second.

I love his descriptions of the different phenomena like symmetriads. One of the few books I've read that describes a truly alien intelligence. The often recommend Blindsight being the other one I can think of.
