Hmmm, Star Trek? I suspect R2-D2 was either in the launch bay in the first ship, or either in that ice plannet base thing. I have yet to see ROTF. But I also request screeencaps for both movies, please.
Gawd, you know some "fanboy" is going to come on here with "I TOTALLY KNEW IT" and become the biggest ass of the fandom trying to rub it in everyone's faces. It's going to happen....just wait....
In the desert scene eh? I think the shot of 'debris' orbiting the pyramid is the first place to look.
R2-D2 was in Star Trek, too! In ROTF, I'm betting he's in one of the more crazy hard-to-spot scenes (like when Demolishor is tearing up the road or Devastator is sucking up everything).
