Did You Know?


The image of the STAR Labs Hall and Hangar building that supposedly becomes the Hall of Justice was a CGI manipulation of photos of the old Union Station in Cincinnati, Ohio. The former train station (now a museum) was the inspiration for the Hall of Justice in the original 70's Super Friends (1973) cartoon. When Barry tells Thea he owns the hall and hanger, she tells him he should do something with it which might foreshadow a CW version of "Justice League". See more »


When Barry introduces Supergirl and she levitates to prove her alien nature, she also uses her heat vision to burn her family crest into the floor behind the rest of the team. No one looks at what she's doing, only looking at her, which they should as, from their positions, her heat vision would have had to cut through Professor Stein. The heat-vision effect was added in post and not originally scripted. Later in story-time, Barry has to explain Kara's heat vision to Oliver quickly in battle, which he should know from the aforementioned introduction. Complicated by that explanation being depicted twice. See more »


[first lines]
Green Arrow: Oh, wow! You really did it this time, Barry.
The Flash: Seriously?
Green Arrow: Yeah, yeah. Yeah, seriously! You to come to Star City, ask for my help, and then, inevitably, immediately, we end up the creek!

Holy f#&@ing s&#t
30 November 2016 | by moustachenickSee all my reviews

The only thing I need to do right now is slow clap.. My expectations weren't high because Arrow has been going downhill and Supergirl and the Legends are really bad, but this episode was amazing and they totally pulled this crossover thing off. I also loved how they fitted the Flashpoint storyline in there and Barry's message from the future. Looking forward to the next one P.S.: There's no need to watch Supergirl S02E08.. It has nothing to do with the crossover and it was boring as hell

Seriously I don't have anything else to say but I need to pass 10 lines so that my review can be submitted.. Is it OK now IMDb??? Is it long enough??
