Spend it on Metro fare and head to College Park on Friday for “Ali: Tbe Myth, The Man, The People’s Champ.” At a time when certain athletes are reminding us how destructive they can be (*cough* Tim Hardaway *cough*), Vincent Cook’s free one-man show might serve as a reminder that the bully pulpit offered by superstardom can sometimes be used for good.

On Wednesday, check out what’s rotting beneath the whited sepulcher of American suburbia at the last night of “The Grass Ain’t Greener” film series at the National Building Mueseum at 401 F St., N.W. Previous screenings have been of “American Beauty” and “Safe,” and tonight wraps it all up with “Poltergeist,” where the ghosts that haunt the picket fences are quite real.

Check out Synetic Theatre’s production of Shakespeare’s “Macbeth,” on from Thursday to Sunday at the Rosslyn Spectrum Theatre at 1611 N. Kent St. in Arlington, Va., (two blocks from the Rosslyn Metro station). The twist on this particular rendition of the play is that it is silent. Founders Paata and Irina Tsikurishvili tend to be idiosyncratic and very physical, so prepare for a visual extravaganza.
