According to Industrial Light and Magic (ILM) special effects supervisor, Scott Farrar, R2-D2 made a cameo appearance in Transformers 2.
There’s an R2-D2 flying around in there somewhere. There’s a little bit of space junk thrown in there; see if you can find it. It’s a scene in the desert.
And that desert scene (check out the pics after the jump) is 2 hours 17 minutes and 52 seconds into the movie. ILM is apparently going to be putting R2-D2 in every movie they make form now on.
Thanks Gizmodo for the tip!
