But the R2 and Yoda thing is also something I thought of the other day.
ROTS is a very good film though. I fucking love it. Seen it about 7 times now(5 on DVD

All I have to do now is get my other half to watch episode 2, then we can go to the cinema and watch it again. The way it's meant to be seen, on the big screen! (see what I done there...it rhymes!!)
