I watched some of the scenes being filmed for this movie in 1960 when I worked at Barker Brothers warehouse. That is in Los Angeles, not Boston. The building at 530 Molina at the intersection of Palmetto Street in the Warehouse District East of Alameda Street was the location for the Brink's building. Barker Brothers warehouse is across the street from there. The scenes looking out the hotel window at the building being robbed were filmed from a furniture warehouse. You can Google the 530 address and see that the building is still there and Barker Brothers old closed warehouse which was supposed to be the hotel ground floor entrance is also still there. The building North of there was also used as the hotel exterior. The movie rings true throughout. It has good characters and many familiar character actors appearing in this fast paced black and white film. The production is not cheap but it is primitive compared to today's explosion circus atmosphere norm. I highly recommend this if you like the old Cagney/Bogart/Raft movies. Look for great old cars that were new at the time the movie was being made.
