Forming a theater company is a bold move; ending a successful one is even bolder. A hat tip, then, to Scott Alan Evans, a founding member of TACT (The Actors Company Theatre) who, over the past quarter century, has produced and/or directed more than 150 productions for the company. Having declared the troupe’s artistic mission accomplished, Evans takes a final bow with an uneven production of a new work, Three Wise Guys, which he not only directs, but also co-wrote, with screenwriter and occasional lyricist Jeffrey Couchman.
