Actors Tom Picasso, playing the part of Caractacus Potts, and Breanna Pine, playing the part of Truly Scrumptious, hold on as Chitty Chitty Bang Bang's wings take them into during a dress rehearsal for Chitty Chitty Bang Bang on Wednesday, Feb. 17, 2016 at the Lawrence Arts Center. The musical, which is directed by Ric Averill, opens Friday at 7:30 p.m.

This weekend in Lawrence: a “truly scrumptious” musical makes its Lawrence Arts Center debut, model-train enthusiasts congregate at the fairgrounds, chili (with the fixin’s) is ladled out at the American Legion, and Douglas County CASA gets in the groove with a Zumbathon.

“Chitty Chitty Bang Bang”

7:30 p.m. Friday, Lawrence Arts Center, 940 New Hampshire St.

The “truly scrumptious” musical makes its Lawrence Arts Center debut this weekend, complete with endearingly quirky heroes, dastardly villains, witty lyrics and live music by the Free State Liberation Orchestra.

The stage musical, for those who missed the 1968 film adaptation, loosely follows Ian Fleming’s original tale of an oddball inventor and his children whose magical, flying car transports them through a series of harrowing adventures.

The show runs through Feb. 28 at the Arts Center, with the first performance slated for 7:30 p.m. Friday. Tickets range from $10 to $25, and can be purchased at www.lawrenceartscenter.org or at the Arts Center box office.
