I just got back from watching the One Man Star Wars Trilogy, and let me tell you...
I was my ass off! There was no music, no special effects, nada! Just this guy on stage going through ALL the music and sounds and voices of all the characters for all three original episodes.
You'll find yourself mouthing through some of the dialogue along with him, you geeks! All the scenes from the movies will come right back to you in a comedic fashion.
He also does a One Man Lord of the Rings Trilogy, and it was reported that during one of his performances, Sir Ian McKellen was in the audience. And, after the show, Gandalf actually invited him to perform his show for the cast.
His name is Charles Ross, a self proclaimed geek, and brilliant performer.
Aside: Nice to run into tostitos at the end of the show too.
