Located at Six Corners in thePortage Park neighborhood ofChicago's Northwest Side, thePortage Theater is one of the oldest movie houses in Chicago. The Portage Theater opened on December 11, 1920 as the Portage Park Theatre (the former name is still visible on the building's facade). Built for the Ascher Brothers circuit with 1,938 seats, the Portage was the first theater built specifically for film (and notvaudeville) in the area.

The Portage Theater's interior features a megaphone-shapedauditorium based on a formalBeaux-Arts opera house design. When the theater was taken over by Balaban and Katz in 1940, its marquee, entrance lobby andfoyer were redecorated in a sleek, streamlined art decostyle to complement other prominent art deco designs atSix Corners such as Searsdepartment store and the Klee Brothers building.

The Portage remained a popular fixture of the neighborhood, becoming a second-run movie house in the 1960s. In the 1980s, the theater underwent a dramatic change when a wall was constructed down the middle of the existing auditorium, resulting in two oddly-shaped cinemas. The Portage was shuttered in 2001 after operating sporadically for the previous couple years. The theater was restored and renovated, and reopened after a five-year hiatus in the spring of 2006 as a single-screen, 1300-plus seat theater showing both silent and sound classic motion pictures as well as hosting other live events.

Today the historic Portage Theater is the home of the Silent Film Society of Chicago, The Northwest Chicago Film Society[3] and hosts the Chicago Silent Film Festival as well as portions of the Chicago Polish Film Festival. In addition, the interior of the theater was utilized extensively in late May 2008 for filming of scenes for the film Public Enemies (2009 film) which is based on the life of 1930's bank robber John Dillinger. The interior of the Portage was reportedly used as a stand-in for the Biograph Theater on Lincoln Avenue, where Dillinger enjoyed his last movie before being fatally wounded by FBI agents upon exiting the theater.
