I have not seen any movies based off Asimov's work...and I never will.
I am trying to build a sizable collection of his works. My next step is to get the rest of the Foundation series and finish that off.
To get all of the robot short stories, you'll need the following:
The Complete Robot
Robot Dreams
Robot Visions
Gold
These collectively have all the short stories ever published. There's a lot of overlap, and the middle two titles are only really necessary for a story found only in their respective titles.
I also highly recommend the Caliban trilogy. These novels were written by Roger MacBride Allen with Dr. Asimov's blessings and cooperation. They are very well done.
There's also a 6-book series called
Robot City, and a sequel 6-book series subtitled
Robots and Aliens. Each novel was written by a different author, all with Dr. Asimov's blessings. The first series is worth reading. The second... I can say it's worth reading because the robots are faced with the challenge "What defines a human?" and causes problems in how the Laws of Robotics are applied. The biggest problem with this series is it features sentient alien life, which isn't supposed to exist by canon.
