I went to this place a few times before it was gutted by fire. Nothing special but not terrible either. I am growing to like these early, small multiplexes more in retrospect than I did at the time. My take on this building is that it is indeed the same structure, just remodeled for a different use. The fire destroyed the inside but I think the overall structure remained intact.

The Farmington 4 Cinemas was owned by the Krim Brothers. Their corporation name was Krim Enterprises Inc. I used to work on and take care of their cars during the mid 70's. Sol Krim was a great guy whom I mostly interacted with. The other two brothers were good people too, Leonard and Mac.
They had another brother out in California who was a well-known Hollywood producer and also went by the nickname Mac Krim who had dated extensively Kim Novak in the mid 50's. I never figured out why the youngest brother always went by his older brother's nick name Mac? All the brothers used to also own and started out with Krim Theater on Woodward Ave. in the 1940's in Highland Park (enclave city in Detroit).
