Northgate 15 Cinemas

It was purchased by Century Theatres in Nov 2001 as part of a 6-theater package:

Century Theatres Buys 6 Theaters in California’s Marin County

November 16th, 2002 ad for renovations in the photo section.

Back in the 70s and 80s, when this was an outdoor mall, the Northgate Theater was a rather large single screen auditorium. I believe it was even outfitted for 70mm presentations, and showed Star Wars in the day. It was located roughly where the food court is located now.

Per the maximum occupancy signs above each auditorium door, seating capacities for the screens are as follows:
1 – 130
2 – 137
3 – 164
4 – 109
5 – 188
6 – 129
7 – 164
8 – 164
9 – 100
10 – 86
11 – 151
12 – 172
13 – 210
14 – 138
15 – unposted.
This puts the total seating capacity at about 2200, if Christian is correct that #15 has about 120 seats.
