If you have seen the movie ...

... Remembered the radio play definitely at the scene of the film. When the film, however, does not know, I imagine it to be more problematic.
The speaker speaks, as another reviewer has mentioned, a little too fast. I kept thinking, why all this is so rushed. Here are some important things are as I think abgeänder / omitted. Here is the most serious:
1. arrives as Eve, is said in the radio play that they float around like a bird. This may be true, but one thing is suppressed here: In the film, EVE begins directly to scan the area and investigate, then flying the spaceship away, EVE is observed until it's gone, and then flies full of joy and motivation (see one of the eyes) going on. This shows that they, as well as Wall-E, is not just a sterile robots, but also has feelings and emotional concerns.
2. When Wall-E is shot through the capsule into space and then exploded, the fire extinguisher is not mentioned a word. What creates WALL-E there, "dancing" with EVE, it can not by itself but fly? Creates confusion in my opinion.
3. Wall-E is not shot down by a laser, as described in the radio play (and you hear a shot), but damaged by a stun gun. That may seem insignificant, but a laser shot would have a far worse effect from, would split into its component parts, the Wall-E for example. Through the shock, however, only his electronic card is damaged.
4. As EVE Wall-E composed (which they do not as described "cautious" makes but fast and accurate) loses his Wall-E "memory" and its emotions. This is described in the radio play though, but the point at which you can see exactly that Wall-E no longer is who he was is that he processed his collected items (Rubik's Cube and bulb among other things) to a waste cubes. This is a great symbolism in the film and is not even mentioned a word here.
About the smaller stuff like that Go-4 Wall-E in the capsule in the film does not look that MO has to bring himself to leave the line or that Wall-E John not rammed, but it falls of its own accord out of his chair, because He also leans too far, can be overlooked. But the four points raised in the film I find really important and I find it incomprehensible that these have been modified.

Nevertheless I forgive 4 stars because the radio play has become quite nice. If you've seen the movie, it's great fun, because you will already reminiscent of the images of the film. The star deduction for the changed things and the little too fast spokesman.
