Personal recollection: I went here many times back in the 70's and 80's. Nothing much to it but it was pretty close to where I lived in those days.

Opened in 1971 for Suburban Detroit Theaters as twin, the Old Orchard I & II, each of the auditoriums could seat 650. The theater opened with "Scrooge" and a reissue of "Doctor Zhivago". The Old Orchard was copied a year later in the Parkway I & II, in Mount Clemens (which was closed in the 80s, and later gutted for retail use). During the late 70s, a third auditorium was tacked on to the Old Orchard (renamed the Old Orchard 1,2,3), bringing total seating to over 1600.
During the 80s, the theater was sold to the AMC chain, which operated it until the late 90s as the AMC Old Orchard 3.
