LIMA — Encore Theatre brings a comedy/musical to the stage today with “Dirty Rotten Scoundrels.” The play follows the 1988 film starring Michael Caine and Steve Martin, who played con men who talked rich ladies out of their money. “That’s the one thing I love about this musical. ‘Dirty Rotten Scoundrels’ is one of my favorite comedies of all times, and the thing that I love about the musical is that it is very faithful to the 1988 film version.
