It's LA Comic Con this weekend, with all the usual panels, performances, sneak peeks and amazing guests that we've come to expect from a great comic book convention. Among the guests are, of course, the stars of The CW's hit shows: Arrow, The Flash, Supergirl, Legends of Tomorrow, and Supernatural. The Arrowverse shows were grouped together for a panel at EW's POPFest event, where executive producer Greg Berlanti spoke alongside Stephen Amell, Grant Gustin, Caity Lotz and Melissa Benoist. On the Supernatural side, Jared Padalecki and Jensen Ackles were on hand to answer fan questions and chat about the show.
In addition to the official panels, the stars got together for a little impromptu photoshoot - one that revealed the hopes at least one star has for a full-on crossover between all five shows.
Amell posted a shot of himself with Gustin, Lotz, Benoist, Padalecki and Ackles on Facebook today, with the caption, "This is the crossover we need." This isn't the first time that the star has voiced his support for a potential crossover episode, and plenty of fans are also hoping to see the shows join forces.
Although Supernatural is not part of the DC TV universe, it's not that difficult to imagine a crossover happening. As well as being on the same network, all five series are filmed in Vancouver, making the practical aspects of a crossover very simple. Amell is also good friends with Padalecki, and the two actors often post photos together; Amell has helped Padalecki with his social media presence and charity campaigns. From a writing perspective, combining the universes might be a little more problematic, although The Flash's multiple realities could come in very useful for this (in the same way that Supergirl was originally connected to the other shows).
It would be a lot of fun to see these five shows interconnect, and there are a lot of ways that it could make sense. With Supernatural's focus on the occult and paranormal events, and Arrow's recent detour into magical foes, it would make sense for Sam and Dean Winchester to head to Star City to check out some of the recent mysterious happenings. Constantine, who appeared in the Arrowverse after his stand-alone series was cancelled, could also return to the show to help connect the two. The Justice League Dark character certainly deals with many of the same monsters and demons as the Winchesters, and if they existed in the same universe, we're sure that these guys would run into each other at some point.
Of course, not every fan agrees with Amell. Many feel that bringing the two universes together would just be complicated, unnecessary, and serve no purpose but to please fans of both series. Like a musical episode (another fan favorite idea) an Arrow/Supernatural episode would exist purely for fun, rather than to really move the plot forward. In addition, while this may be a personal hope of Amell's, it doesn't mean that such a crossover is in the works (unlike the DC TV musical episode, which is confirmed to happen), just that the stars are having a little fun in LA this weekend.
Supergirl Season 2 airs Mondays at 8pm on The CW; The Flash Season 3 airs Tuesdays in the same timeslot; Arrow Season 5 airs on Wednesdays; and Legends of Tomorrow Season 2 airs on Thursdays. Supernatural airs on Thursdays at 9pm on The CW.
