New York City-based theater company Bedlam has been such a frequent visitor to the Boston area, it’s a wonder it hasn’t considered changing area codes. The troupe’s latest production to hit the Hub, Hamlet/Saint Joan, comes to the Emerson Cutler Majestic Theatre March 7–25 as part of ArtsEmerson’s 2017–2018 season. This production is actually a two-in-one, as Shakespeare’s iconic tragedy about the titular melancholy Danish prince runs in repertory with George Bernard Shaw’s ground-breaking drama about Joan of Arc (pictured). For both plays, four actors play all 49 roles in a spare setting that focuses the attention on the playwrights’ classic scripts. And those that want an up-close look at this amazing feat can even opt for on-stage seating, which is available to a lucky few.
