A lot of Toronto in this movie trailer (standing in for NYC of course). The shots along Adelaide Street are way overused though, (scenes featuring 100 Adelaide West under construction in the background). They also CGI'd a building at the end of the street to make look cooler. Also some University Ave. scenes. Saw a TD bank sign too in another scene (although it's authentic to NYC now, since they have them there too)

Suicide Squad seems to be the next big movie being filmed here next month. It'll be interesting to see what exterior scenes they film in the city, depending on what city they choose to set it in. Perhaps it could be Gotham?
