Since Warner Bros. owns the characters that appear on both The CW's Arrowverse shows, like Arrow, The Flash, and Legends of Tomorrow, as well as CBS's Supergirl, fans have been hoping that the two television universes might crossover at some point in the future. However, new comments from executive producer Andrew Kreisberg have revealed that the crossover can never happen because it would be AGAINST THE LAW:
There's always those late nights, delirious, semi-high on pizza where you're like, 'You know what would be really cool? If ...,' But right now there is no legitimate actual plan to bring ['The Flash's'] Cisco [Carlos Valdes] onto 'Supergirl' or to bring ['Supergirl's'] Winn [Jeremy Jordan] onto 'Legends [of Tomorrow].' First of all, we don't even know if we could, legally. And quite frankly, just making the 'Arrow'-verse which is what we call 'Legends,' 'Flash' and 'Arrow' work and then making 'Supergirl' work, it's enough of a challenge without having to add a fourth player.
Like most of our readers, The Outhouse was shocked to learn that there is a law against popular superhero television shows on different networks crossing over with each other, so we spoke to an expert in the field of Legislative Excuse Making, University of DeVry Professor Thaddeus T. Puffinbottoms.
"Oh, of course, that's very illegal," the professor told us while rifling through some very dusty legal texts from his shelf. "It has been since 1896, when U.S. Senator Stufferford P. Killjoy introduced the Liberty for Americans Who Love Freedom Act, which banned the crossing over of popular fictional properties from competing entertainment companies, colloquially known as the Killjoy Act of 1896."
"Of course, television didn't exist back then, or even radio broadcasting, so Killjoy's law was really meant to apply to traveling theater groups, mimes, and old timey strongman acts," Professor Puffinbottoms continued. "However, a Supreme Court ruling in 1963 against the producers of Gunsmoke and Leave It to Beaver set the precedent that all modern media is under the purview of the law."
According to Puffinbottoms, at the time of the law's passing, many legislators regretted their actions and felt the law may have been a mistake, citing a general lack of any sense, as well as Senator Killjoy's reputation as a complete dick head, even by 19th century standards. However, Puffinbottoms said that any attempts to repeal the law were overshadowed by Populist Party politicians calling for the repeal of Grover Clevelandcare, an unpopular health care reform bill that provided taxpayer-funded leeches, ether, and limb amputations for despised Irish laborers.
"The more things change..." Puffinbottoms pointed out.
The bottom line is, it looks like fans of DC's Arrowverse and Supergirlverse are out of luck, and will have to keep crossovers between the two universe strictly in the realm of poorly written fan fiction. We'll keep you updated if anything changes.
