THE LAST DAYS OF MICKEY & JANE | Merrimack Repertory Theatre commissioned this brand new work from prolific Massachusetts native Richard Dresser (Below the Belt, Rounding Third) that has Whitey Bulger written all over it. "Mickey, a witty, paranoid fugitive ex-mobster from Southie who is on the lam with his no-longer young, Charleston-native girlfriend, Jean, is forced into an early retirement in Europe. With his Boston Red Sox cap never out of reach, he is out of place and away from the one thing he truly loves: his work. While he searches for a way to get back into business and Jean longs for a 'normal' life back in Boston, the dysfunctional couple runs into one hilarious situation after another, learning shocking secrets about each other along the way."
