When famous silent movie star Don Lockwood (Nicolas Dromard) falls for aspiring young actress-singer-dancer Kathy Selden (Kate Fahrner), it’s a potential publicity problem: Don is already advertised as romantically with his co-star Lina Lamont (Kim Sava), a catty diva who doesn’t like to be upstaged. And more trouble comes when a rival studio overshadows them by premiering the first talkie. It will take ingenuity, can-do-it-ness, and movie magic to make all the good guys come out on top, in the studio-lot romance of Singin’ in the Rain. Adapted from the classic movie about movie people, it closes out the 60th season Maine State Music Theatre, in a lavish production directed and choreographed by Marc Robin.
