The Agency Theater Collective puts a new spin on Will Kern’s Chicago holiday classic Hellcab. Director Sommer Austin adds a different gender dynamic by casting Rusty Schwimmer as the lonely Windy City cab driver who faces an oddball assortment of passengers in the days leading up to Christmas. Agency Theater Collective’s revival of Hellcab continues through Sunday, Dec. 17, at the Den Theatre, 1333 N. Milwaukee Ave. Tickets are pay-what-you-can, although a donation of $5 to $30 is suggested; visit WeAreTheAgency.org for more info.
