The Circa '21 Dinner Playhouse's production of Boeing-Boeing is a colorful rendition of French playwright Marc Camoletti's classic farce - and that's just the set and costumes. Scenic designer Susan Holgersson's and costume designer Gregory Hiatt's combined use of bright primary and secondary colors is stunning, with Holgersson's seven-door set providing delight even before the opening of this comedy's proverbial curtain.
