No scripts seem to have survived, but stills indicate that a couple of scenes were filmed and then cut, including one in which Stan gives Ollie a shoeshine before they go out on their day of mayhem. One of the crew regulars recalled that at the end of the traffic jam, Stan wanted to show a truck carrying a pole which goes into the window of a limousine and tears the body from the chassis. This shot isn't in the film, but the end result is the chauffeur walking on the road as he 'drives' the chassis. The traffic jam sequence took 4 days to film on a road that now borders the Santa Monica Airport.
Thomas Benton Roberts, playing the part of the Motorist with Tomatoes, was a prop man and carpenter on the Roach lot. The tomato rubbed in his face had been previously cut open and filled with ketchup, so it would film better.
Originally titled "Two Tough Tars."
Oliver runs into a driver that stopped in front of him without warning and asks "Why didn't you put your hand out?" Turns and stops were usually signaled by the driver with hand/arm gestures, but they didn't work well at night. By 1928 (the year of this film), only 11 states required brake lights on cars, but the lights were operated manually by the driver, not automatically by the brake pedal.
Thomas Benton Roberts created several break away cars for this film, including one that fell apart when a certain wire was pulled.
