Theater 2014-15: World premieres, ‘Smokefall’ reprise crown plans for Goodman’s 90th year

14th in a series of season previews: Goodman Theatre has a bountiful 90th season in store, punctuated by a pair of world premieres, an early remounting of Noah Haidle’s “Smokefall” from last season — with returning featured actor Mike Nussbaum, also 90! — and a revival of August Wilson’s “Two Trains Running” that will be enhanced by several related events.
