Did You Know?


This is the first part of a three-part crossover event, continued in Arrow episode 7x9 "Elseworlds, Part 2" or "Elseworlds: Hour Two," and concluded in Supergirl episode 4x9 "Elseworlds, Part 3" or "Elseworlds: Hour Three." This is the first crossover not to include the Legends of Tomorrow since the two part Arrow/Flash crossover that served as a backdoor pilot and introduction of some of the characters "Legends of Yesterday/Legends of Today" in season two of this show and is incidentally a backdoor pilot for Batwoman. It is also the first major fall crossover not to take place in the eighth episode of at least most of the participating shows, instead being the ninth episode of the season for all them. See more »


When Superman is fighting AMAZO, a crowd appears in the background between shots. The camera moves to a close up of Superman, where he exclaims: "that's not good" it cuts back to display both characters, and the crowd of dozens of people suddenly appears. Earlier in the same scene people are walking in the background casually as if nothing is happening. See more »

Enter Elseworlds
10 December 2018 | by ThomasDrufkeSee all my reviews

Aside from a great episode here or there, the past few seasons of these CW shows have been less than stellar. So I look forward to these crossover episodes because I know there isn't much substance beyond these few nights. The beginning of Elseworlds was an exciting one, even if the pacing was much slower than last year's Crisis.

Body swapping humor in movies/TV shows is usually perfect for humor and the first 20 minutes of Oliver/Barry realizing they have switched bodies is pure gold. Hearing Oliver say "You have failed this city" in the Flash suit was incredible, as was watching Barry get payback on Oliver for the arrows in the back from 2014. Oh, and I will never get tired of seeing Diggle puke after seeing or experiencing super speed.

Bringing Superman into the fold only added to the fun. Oliver trying to puff up to Clark? I mean come on. I can only assume they took note from the Starlord/Thor dynamic back in the spring, but it was still a great moment. Which gave Amazo just one more ability to copy and emulate, which was a cool action sequence, even if I could have used a more layered villain to kick off the crossover.

We'll see how the next two nights turn out but boy was this a fun kick off to the 5th (and technically 6th) crossover of the Arrowverse.
