Cue music: Dum. DUM. Dum dum dum DUUM dum. Dum dum dum DUUM dum. Dum dum dum dummmm….

If that makes any sense to you, you’re probably the target of Charles Ross’s uproarious One Man Star Wars Trilogy, now making a return engagement in D.C. at Woolly Mammoth Theater. The show’s exactly what it sounds like — Ross acts out just about every scene of the three original films with gusto, even humming the movements of the soundtrack — and he only needs 60 minutes to pull it off.

The result is hysterical for hardcore fans, more than entertaining for those casually familiar with the films, and probably a little confusing if you haven’t seen the movies (but really, guys, if not, it’s about time). Ross is a very talented entertainer — his voice shifts easily into an amalgam of different impressions (C3PO’s impressive; Vader isn’t, but still amuses), and he’s got a boundless energy that has him leaping across the stage, simulating battle scenes and space ship confrontations.
