Adapted from David Sedaris' famed audio presentation and subsequent short story, The Santaland Diaries - the latest endeavor from My Verona Productions, currently playing at Rock Island's ComedySportz venue - is an acting triumph for its star, Adam Lewis. Playing an unmotivated 33-year-old who finds himself - to his abject shame - employed at Macy's as one of Santa's elves, Lewis is spectacular; as he enacts his character's grueling ordeals in a one-man show that's part monologue, part stand-up routine, and part performance-art piece, the actor is thrilling to watch, so brilliantly focused and ceaselessly inventive that he leaves you a bit in awe.
