The Alternate Movie Title Game (Sci Fi Edition)

Here are the rules: We will provide an "alternate title" for a film and ask you to name the actual film. Most of these are pretty easy. Please answer no more than three questions per day so others can play. You may have an answer other than the intended one--just be able to defend it!

2. Robby & Timmie.

3. The Computer That Ruled the World.

4. Eloi Ahoy!

5. Code Name: Wildfire.
