While "Avengers: Doomsday" didn't reveal much plot information during this year's San Diego Comic-Con (SDCC), Marvel's massive promotional advertisement for the film sparked controversy over safety concerns, ultimately leading to a $160,000 fine from the City of San Diego. 
According to the San Diego Union-Tribune, the advertisement completely covered the arches in San Diego's Gaslamp Quarter, a location the city had previously formally rejected due to concerns that the ad's structure could pose safety risks and impede pedestrian flow during the city's largest annual event.
Despite the rejection, Marvel and its marketing partner, outdoor advertising company Elevue Outdoor, proceeded with the installation and display, causing fines to accumulate daily.
Richard Berg, a spokesperson for the City of San Diego, stated that the contractor was aware of the safety risks but refused to address them, resulting in the legal imposition of fines. The report noted that while the city frequently issues penalties for advertising violations, the $160,000 sum is unusually high. This was primarily because the advertisement remained suspended for six consecutive days, with daily fines escalating to $50,000 in the later stages. In contrast, the total fines issued by the city for advertising violations throughout the entire SDCC period last year amounted to less than $25,000.
